MYOG Cuben/Momentum Quilt

[Evan Chartier]

src="/backpackinglight/user_uploads/1269330591_23002.jpg" width="550" />All right guys, finished the quilt! Thanks to Tim and everyone else that helped me out with the design and logistics. Final specs: 78" length by 49" head straight taper to 37" foot. 2.5" loft with 5.5" baffles. Weighs 16.2oz. Made with cuben fiber .51/.6oz (depending on who you ask) weight shell and baffles CT1K.08, with a 8in strip of momentum.

It looks great. Awesome work!

Evan, very nice work.

A few details: How much down did you end up using and at what height is the baffle material (not the loft, but the actual baffle)?

[Evan Chartier]

Thanks guys! I used 12 ounces of down, possibly 12.1 ounces. I made the baffles 3.5 inches tall before the seams, finished height was about 2.5 inches. I didnt know how big to make them, but I was aiming for 2.5 inches of loft, so I made 2.5 inch baffles.
Loving this!
San Diego tomorrow, PCT here I come!

Great job! How much did materials end up costing you? Is it down? I may have a new project on my hands….

[Evan Chartier]

John,
Yes it is down. The materials cost (by unit) 20.25 per meter of cuben, 5 dollars thread, 5 dollars needles, and 150 USD thru-hiker quilt kit (5 yds momentum, 2 mesh, 12 down). Total cost: Approx. 261.25 USD however this is with tons of momentum, mesh, and some cuben left over. Also, this is the price of CT1K.08 weight cuben from Cubic Tech and does not include shipping and handling for any materials, but the lighter weight .33oz would be cheaper. Buying cuben from quest or zpacks will cost more, so I would suggest trying to find someone to split the minimum order of 9yds with you from cubic tech like I did. If I didnt get the cubic tech order, I would probably have gone with the zpacks CT1K.08, their price is very good and Joe is great. But going with cubic tech will bring the cost down considerably.
Its pretty economical. I was able to get the quilt and vest materials for 260 USD, and I still have approx. 30-40 dollars worth of materials I could sell back. I was planning on spending much more for a sleeping bag, and am already on a super tight budget, so it worked out well.
If you do end up making one feel free to shoot any questions my way and I will try to help, assuming I am on the computer (probably not the next few months!) Tim and everyone on the site were really great in helping me out with making it as well.
Take Care!

for your detailed reply. Thinking about a new quilt for a possible CT hike. I'll get my current projects taken care of, then see where I'm at. This looks doable, and I could use the leftovers for a momentum/sil/mesh summer bivy.

Have a great time!

Evan,

That looks very nice. I think that is my next MYOG project. Just out of curiousity why did you buy the thruhiker quilt kit insted of the supplies seperately after you had the Cuben?

Greg,
I didnt really know what I was going to make the quilt out of until I got the cuben in the mail. When I did the math I found that it was almost the same price to get the cuben and thru hiker kit then to get the materials seperately. I would need an unbroken piece of momentum 90 of 2.5 yards and thought it would be cheaper this way (unless I wanted to seam in the middle). But I think it worked out well. How much do you think it would be to get the stuff seperately? I dont think I did a good job of pricing that out properly…

Evan,

I don't remember exact prices but I think I paid about $8/oz through a local company for 850 down and $13/yd for the momentum at thruhiker. The other materials would be the same.

I guess I would have just seemed it in the middle since you already have seam lines for the baffles. This way you would need less than 2 lineal feet of momentum.

So looking at it from the perspective of no seam, and all the extra material you now have for other projects, it was probably a good way to go!

It looks like a very nice quilt.

If I do this too, I may also order the t-h kit, just to have the instructions, patterns, etc. because I know I can use the extra fabric.

The only thing I'm concerned about is the vapor barrier effect in higher temperatures. It seems that might make a cuben quilt less versatile. Maybe another strip of momentum on the underside for a warmer-weather bag? Evan's should go down to 0 based on the loft alone*, forget the VB, and I'm not sure if I need to make something that warm. Can anyone who has a warmer-weather enLightened bag say how they feel about the VB?

[Evan Chartier]

Greg,
Yeah it would be a little cheaper to order less and use the seam. Going the other way though (no seam and extra fabric) the kit is the way to go. 8/oz is the same as thru-hiker I believe, but with the kit its all a bit cheaper I think. Really great!
John,
Not sure if this touches on what you were talking about, but the thru-hiker "quilt instructions" are posted online and not very extensive, meaning there is no real pattern. Ordering the kit only gets you some of the materials.
So far I have had no problems whatso ever with the quilt in higher temperatures, meaning in my house and in San Diego. Its been great! Never been more than comfortably warm even.
If its really warm/hot (more than 65 deg) I would probabaly just go without the quilt.
Momentum strip on the inside=vapor entering the down (theoretically). Probably not the best idea, but it could work for you.
Try sleeping in a trash bag or under a waterproof tarp (rolled around you like a boritto) in the house to see the warm weather VB effects. Worked for me, I thought it was great.
Good luck! Headed out to the border in an hour…
