Quilt Trip: An Examination of UL Backpacking Quilts

Earlier, Ploss and I had an email discussion about backpacking quilts – specifically, the enLIGHTened equipment Epiphany quilt which purports (correctly) to be the world’s lightest backpacking quilt. How does it achieve this distinction? Cuben fiber, baby! Before I place my advance order (would if I could) let’s take a look at some of the comparable quilts on the market, see how the various materials used stack up, and envision how they might compare against some of the lightest traditional mummy bags on the market today.

Learning about Cuben, having some food

As a…satisfied owner of the now defunct BPL Cocoon Pro 90 Quilt I’ve come to appreciate the freedom, flexibility and significant weight savings a quilt has to offer, but the reality is that the 11 oz. synthetic Pro 90 is merely adequate to the task at temperatures above 50 degrees, and I have yet to use it without having a down jacket/pants set at least on hand. Down fill obviously offers greater warmth at a lower weight, but it’s crucial to keep down quilts and sleeping bags dry; a waterproof, or extremely water resistant, shell is required lest you find yourself cold, wet, and carrying a double-weight soaker. Cuben Fiber is perhaps the ultimate primary shell material available, originally designed for America’s Cup racing sails:

It is 50% lighter than Kevlar, four times more durable than Kevlar and lasts as long as Spectra and remarkable weighs less than 1/2 oz. per square yard.  It flexes without loosing strength.   Cuben Fiber is a laminated fabric constructed from plasma treated Ultra High Molecular Weight Polyethylene (UHMWPE)  fibers and monofilament polyester film.  Cuben Fiber retains 100% of its original strength after being folded 250 times.  It is not effected by salt water nor does it soak up water.  It has great UV resistance and is extremely water resistant.  Uses: great for extremely lightweight tarps, rain gear, stuff sacks, packcovers.

Despite this glowing endorsement, Cuben fiber remains a fringe material for your everyday backpacker for whom concerns about durability persist; it’s not necessarily as puncture resistant as some would prefer, and as with most ultralight equipment a high level of attention to care is required to maintain the integrity of the material.

Ice Cube is not about a punctured bag

Originally I had intended this post to cover some of the key differences between a quilt and your typical mummy bag, but I probably can’t add much that Steve Evans didn’t cover in the video referenced above, nor that you could explore  from the expert community at Backpacking Light. Instead, I’m merely going to cover some of the backpacking quilt options available in order to highlight how significantly weight can be reduced with the use of Cuben fiber/Momentum 90 for the shell, and down fill.

Mark Cuban believes this post is gratuitous

For the sake of the comparisons below, for the Epiphany I’m assuming a sized Medium 0.33 oz/yd2 Cuben/800+ down fill w/2″ loft, “rated” to ~40 degrees (ratings being subjective at best and arbitrary at worst) which should weigh in near 11 oz – remarkably the same weight as my aforementioned summer season BPL Cocoon Pro 90. Please note: the products listed below are chosen for their relative comparable length and temperature rating. I’ve chosen to compare quilts a 6′ man such as McLovin could use comfortably near 40 degrees. A  very short list of  said comparable backpacking quilts on the market today:

Brand Model Shell/Fill Price Weight
enLIGHTened equipment Epiphany Cuben+Momentum/800+ Down $400* 11 oz.**
GoLite Ultralight 3-Season Waterproof-Breathable Pertex/800+ Down $275 25 oz.
Jacks R Better Shenandoah DWR Nylon/800+ Down $190 15 oz.
Mountain Laurel Designs Spirit (45 deg.) Momentum Taffeta 20d X 20D DWR/2010 Climashield Apex $185 14.5
Nunatak Arc Edge 0.8 oz. Quantum/800+ Down $332 11 oz.

*Product not currently available; suggested price
**Estimated weight

It’s important to note that several of these products e.g. the Arc Edge, are listed with their stock length which is several inches shorter than McLovin would actually prefer. At a glance, the Jacks R Better Shenandoah would probably get the early nod for best bargain at $190, 15 oz., and 800+ down fill rated to at least 40 degrees with a 2″ loft; the MLD Spirit is effectively a summer bag only in the 45 degree model listed above, but an 18.5 oz. (regular) 30 degree alternative is a mere $200. In all, each of the quilts listed offers a little something different depending upon your particular needs, and you should peruse all of the variations available from these generally cottage manufacturers, as I’ve listed only a tiny sample of the quilts they have to offer.

Q*Bert waits patiently for his cottage gear

So why would I consider spending twice what I could pay for a JRB or MLD quilt in order to have a slightly lighter model from enLIGHTened equipment? Cuben baby! But not necessarily because I’m riding the space-age material bandwagon (I am). No, what I really am looking for is the roomiest, lightest, warmest and waterproofiest quilt available, one that will afford me the opportunity to reduce my clothing weight (carried) on appropriate occasions, without undue concern about getting the thing wet. Given Cuben fiber’s water-resistant vapor barrier characteristics, the at least hypothetical opportunity to use it into near freezing temperatures, the comfort only a quilt can provide inside of a bivy sack, and the flexibility to combine with shoulder season down insulating layers as desired, the Epiphany meets all of my requirements for a single, versatile multi-season sleeping solution.

MLD eVent Rain Mitts Quick Review

After a bone-chilling hike in a downpour @ 38 degrees a week and a few days ago, forcing me to throw my poles into my pack and bury my hands in my pockets, I immediately decided that I needed some lightweight shells to protect my hands in ultralight style! What better excuse, er reason, to send $45 on some new MLD eVent Rain Mitts! I recognize that I could have simply worn my possomdown gloves, letting them get absolutely soaked, but that would have required me to shed my pack, exhume my gear pouch, and sort through my all of my packed clothes!

As is typical for accessory purchases, I received my mitts in less than a week from Ron @ MLD, and received them prior to my next weekly 6am hike with McLovin! Constructed entirely of eVent fabric with an ergonomic shape to reduce seam strain when using poles, I was immediately impressed with the construction and weight (in size medium) of less than one ounce for a pair!

I wore them on a ~7 mile hike on Friday morning and found that they kept my hands really, really warm in ~40 degree weather. In fact, they kept me so warm that I shed them about half-way through the hike! As would be expected of eVent fabric, there was absolutely no condensation at all, even though I created quite a humid environment inside.

Items required for seam-sealing: McNett Seam Grip and Talcum Powder!

Seam Sealing:

Have I ever mentioned that I HATE seam sealing? If I didn’t, I meant to. To strengthen the seams and make the mitts fully waterproof, it is recommended to seal the seams of these mitts using McNett Seam Grip. To do this, you need to flatten the seams by packing the gloves from the inside out using paper towels, newspaper, cloths or anything that’s handy. I loaded the mitts with paper towels and tightened the cordlocks, preparing it for seam sealing. It’s a pain and nearly impossible to get totally flat seams, but it’s worth the effort otherwise it will be extremely to do even a moderately professional job.

Running a thin line of Seam Grip along the edge and thumb seams was difficult at best, but I was able to effectively seal them in a messy fashion. I threw out the idea of having a real professional look when I first opened the mailbag and saw the sealer . . .. Oh well, I was done and all that was left was to hang them overnight to dry.

Sealed and ready to go!

Got Baby Powder?:

Seam Grip, once dried, creates a very rubbery seal on the mitts that sticks to itself. This can cause the sealer to pull apart if the mitts are stored together, which I’ll note, is the only way to store items that are intended to be used together! To prevent this, all that’s required is to lightly dust the seams with talcum powder. This prevents the seams from sticking and completes the mitts for use!

Parting Thoughts:

  • Yet another well thought-out and constructed product from Mountain Laurel Designs!
  • They weigh an extremely light 1.25 oz when sealed, which is very light for a product that can replace gloves for most backpacking use. I’ll note that these are only a few tenths of an ounce lighter than possomdown gloves, so depending upon the weather can either be used by themselves or in conjuction with gloves for use in freezing conditions.
  • Did I say that I HATE seam sealing?
  • I highly recommend these mitts for backpacking use! They work very well in conjunction with hiking poles due to the ergonomic shape and it’s easy to tighten the cordlocks with the mitts on!

MLD Cuben Solo Pro Tarp Quick Review

One of the cuben items purchased for this season is a Mountain Laurel Designs (MLD) Solo Pro Tarp. This, although I didn’t necessarily “need” a new tarp, was intended to be used in conjunction with my Super Mica jacket to replace my Gatewood Cape and wind shirt in my kit, shaving a couple of precious ounces and operating as a more versatile combination. 

I’ve ordered several items from Ron at MLD over the past couple of seasons and placed an order for a Solo Pro Tarp on March 19th. Surprisingly, I received my tarp in only just over a week, which is rare given that there’s typically a 6-8 week backlog in orders leading up to hiking season. My tarp, in its yellow silnylon stuff sack, weighed in at 5.0 ounces (including lines and linelocks). By replacing the silnylon sack with a Mini / Tarp Stuff Sack built by Joe at Zpacks, I reduced the total weight down to 4.75 ounces. Yeah, I could probably lose the stuff sack altogether, but I’m somewhat retentive in that regard.

Just a little stuffy. Stuff, stuff, stuffaroo!

Setup:

I found the setup to be as easy as any tarp. I anchored the rear corner tie-outs loosely and looped the front ridgeline tie-out around the front hiking pole in a triangular configuration, extending the line to the ground. I next setup the rear ridgeline tie-out, also looping it once around the pole. I next placed the front corner tie-outs and tightened all of the ridgelines using the linelocks for a taught pitch.

One single loop is all that's required for the ridgeline!

Ahhhh . . . catenary ridgeline!

There's a lot of space under the tarp for pack, bivy, etc.

 Initial Thoughts:

  • The bonded ridgeline is really strong and I found it easy to get a taught pitch.
  • There’s a lot of space under the tarp for all of one’s kit!
  • At ONLY $159, this is the lowest priced cuben solo tarp around.
  • Like all of MLD’s products, the tarp is extremely well made with excellent attention to detail.
  • I will need to wrap some duct tape around my poles in a couple of places for alternative ridgeline heights, especially for grim weather.

I would recommend this tarp for anyone looking to lighten their shelter load. If you’re looking for the lightest solo shelter on the market, constructed entirely of cuben fiber, this should be your choice!

Marmot Super Mica Review

I’ve made MANY purchases for the 2010 backpacking season, including significant purchases of gear constructed of cuben fiber. I’ve not yet chronicled a single item thus far, due to the simple reason of not wanting to review anything I haven’t adequately tested . . . in the field. The first purchase that I feel able to properly review is the Marmot Super Mica, an ultralight jacket that I purchased in early February. This purchase was intended to fill a void in my UL collection for a full-featured jacket that I could don as both a windshirt and storm-proof jacket given its low stated weight of 9 ounces from the description @ Marmot.

Introducing the Marmot Super Mica!

Prior to my purchase, I was intrigued with its manufacturing specifications, which fully met my needs:

Marmot MemBrain® Waterproof/Breathable Fabric
Micro-Stitched and 100% Seam Taped – for maximum waterproof protection
Gale-force Hood with Laminated Wire Brim
ERG Hood Adjustment System
Water-Resistant CF Zipper
PitZips™ with Water Resistant Zippers
Pack Pockets™ with Water-resistant Zippers
Duralite Zonal Reinforcements
Asymmetric Cuffs with Velcro Adjustment
Integrated Cooling Vents
Reflective Logos
Elastic Draw Cord Hem – For Adjustability in Serious Weather
Angel-Wing Movement™ – Allows Full Range of Motion in Arms so Jacket Doesn’t Ride Up

The features are a significant upgrade over the prior generation, the Mica, in the areas of an upgraded hood with wire brim, reinforcements on the shoulder strap and hip belt areas, pit zips, and pockets that are placed above the hip belt area (that, I’ll note, also operate as additional vents).

Size/Weight:
I was happy to find, upon throwing this jacket on the scale that it weighed only 8 oz in size medium. At 5’9″and ~165 lbs, the jacket fits me perfectly and is suitable for layering over base and insulation layers as appropriate. This was key for me as I didn’t want too athletic of a fit given my intent to use this as my primary shell for backpacking.
 
Testing:
I performed testing of this jacket with 3 separate packs, in myriad weather conditions including torrential downpours, heavy wind, and wind-blown snow, for greater than 60 miles of backpacking. I found the breathability of this jacket to be excellent, other than in my forearms. Given multiple venting options, I was able to address this by loosening the cuff appropriately. I found it to be extremely weatherproof as well, withstanding a multiple hour downpour with nary a drop inside. That said, the cuffs, the only area that isn’t fully seam taped, got pretty wet, but not enough to soak through (and it was raining really, really hard).

One of the tests that I performed was to walk through a waterfall in the trail to determine whether any water would penetrate the pack. I’m happy to say that the jacket passed this test with flying colors and other than a cold rush of water between my pack and the jacket, I escaped unscathed!

On top of Camp Smokey . . ..

 Conclusions:
  • This jacket is expensive @ $200, but is extremely light and fully-featured providing a ton of options without a significant weight penalty.
  • It withstood significant pounding from the elements (rain, sleet, snow, wind) while keeping me completely dry.
  • This provides a level of function that I wouldn’t have with a poncho-tarp combination and is similar weight when combined with a UL tarp (to be reviewed separately).
  • The hood is very adjustable and keeps the elements OUT. The wire brim is flexible enough to be used without a lid or visor.
  • The pockets are easily accessible when using a hip belt.
  • The rear of the jacket is slightly longer than the front, keeping one’s “coin slot” under wraps (if only Franken would buy one of these . . ..)
  • We’ll see how the reinforcements fare over time, but at this point there’s no apparent wear.

I’ll plan to perform significant additional testing over the coming months, but at this point, in spite of the number of miles that I’ve put on it, the jacket still looks brand new.

EDIT: Given a comment below, I’ve added an additional photo of the Super Mica when loosely rolled up for storage.

BPL Stix Mod: Redux

This is merely an addendum to Ploss’ post BPL STIX Mod: Aftermarket Tips from July 2009, which details how to properly add Leki aftermarket tips to these UL trekking poles. I’ve been resisting implementing this mod despite my fear of wrecking these apparent collector’s items (no longer offered from BPL as of February ’10) because, frankly, they were perfect – at 120cm they offered the sweet spot of length both uphill and down (McLovin is a hair over 6′ tall). Tough to mess with what’s not broken – yet!?

Reality was that the mod was much less punitive than I feared, both in added length and the completely negligible weight, and the process itself was as simple as Ploss suggested.

Length added: 3.8 cm exactly to 123.8 cm
Weight added: 0.2 oz. (5.7g) to 4.7 oz (per pole)

Before and After - er, After and Before (L to R)

This length will actually be closer to what I have used previously with my collapsible Black Diamond poles for use with the Gatewood Cape (shelter pole), and I’m looking forward to testing them on trail later this week. – MCL

BPL Firelite Esbit Wing Stove Review

Can this titanium solid fuel stove compete with the blogger’s favorite, the White Box Stove? Can it boil enough h2O for two? A (non-field) full test and comparison.

Goal: boil 16 oz. (2 cups) of water using one .5 oz. Esbit cube AND/OR .5 oz. denatured alcohol
Conditions: 54 degrees, light wind at 860 feet

The kit. Not pictured: GSI Hae Tea Kettle (used w/White Box)

The plan: see how the 0.40 oz. Backpacking Light Firelite Titanium Esbit Wing stove + a single .5 oz. Esbit fuel cube fared against the 2.5 oz. White Box Stove + .5 oz. denatured alcohol for boiling 16 oz. of water.

Unwrapped Esbit smells like low tide. Pelican alert!

Observations: the Firelite Esbit Wing Stove is crazy light, and is perfectly designed to do one thing: deliver burning Esbit solid fuel. Esbit comes in foil packages reminiscent of that 70′s era liquid center gum your Mom used to rock, and immediately you’ll notice two shortcomings vs. an alcohol stove: first, these things stink. Not in the package so much, but in bear country I’d definitely bag & hang ‘em – think pickled herring. Second, you’ll need matches or a lighter to get it burning – not a deal breaker certainly, but a far cry from the ease of lighting an alcohol stove with a firesteel tool like the Spark-Lite Firestarter, as I did with the white box for this test.

Firelite SUL-900 Titanium pot fit on the stove like a glove

It was a little breezy so I added a windscreen – specifically the one that ships with the White Box stove. I felt like I was cheating on my White Box stove – you know I love you White Box baby! – but as my experience has been that the White Box rarely if ever needs a windscreen, chalk this up as another “knock” against the Esbit Wing Stove.

Get on with it. How long did it take? Virtually everything I’ve read about Esbit fuel cubes is based upon boiling 8 oz. of water, making it essentially a solo stove, but as the burn time was listed as “up to 15 minutes” I was hopeful that it would be capable of bringing 16 oz. to boil. Which it did, in 9 minutes 10 seconds. Success! It furthermore had a total burn time of 15 minutes 45 seconds, leading me to conclude that, at least under today’s conditions and altitude, one Esbit cube with this particular kit could boil at least 18 ounces or more. By comparison, the White Box stove + the GSI Hae Tea Kettle, sans wind screen, brought 16 oz. of water to a boil in 6:45 (m:s)  and consumed ~.5 oz. of denatured alcohol in 9:42 of total burn time – again, more than enough time to boil at least 18 oz. of water under similar conditions.

Stove Weight
Fuel Cookware Boil
Burn
Requirements:
BPL Firelite
Esbit Wing Stove
0.4 oz. 0.5 oz. Esbit cube BPL Firelite SUL-900
32 oz. pot
9:10 15:45 Windscreen;
lighter/ matches
White Box Stove 2.5 oz. 0.5 oz. denatured
alcohol
GSI Hae Tea Kettle
(1 qt.)
6:45 9:42 fuel container

Conclusions: While I still have to give the overall nod to the White Box Stove for performance and reliability – it hasn’t FAILed me yet – I was quite impressed with the ability of the solid fuel stove to deliver 2 cups of boiled water with a single cube. Given its reputation for superior cold weather performance vs. alcohol stoves, the Firelite Esbit Wing Stove will undoubtedly find its way into my winter kit as a backup stove at a minimum, and with a total weight savings of ~3 oz. (including fuel bottle) it will likely find its way into my regular kit mix as well. Grade: recommended.

Update: went vertical eh like 3 weeks back, up to about 4100′ with the idea of firing up Ploss’ BushBuddy stove + titanium grill to rock some trail steaks. Foot of snow and nothing even close to burnable tinder/wood later…thank Jah I brought the Esbit wing stove. Operating in roughly 30 degree conditions the Esbit worked it, boiling 2 cups of water easily for some backup freeze-dried chicken & potatoes handily. That is to say I made my beotch Ploss make my effing dinner for me. Good Ploss. But I digress. Setup on the snow on top of an inverted titanium sierra cup w/foil windscreen, this stove moved ahead of the White Box Stove as a candidate for week long trips, especially given the opportunity to cache Esbit tabs along with my food in cacheable areas.
