I don't care about form either in the woods, functionally speaking the quilt needs a hood to cover my head on colder nights, the foot box is only some velcro, I was trying something out and it didn't really work how I wanted it to, and the down doesn't stay in place. I karo stepped the quilt and I think with the amount of down I put in it the spacing is too far apart. The quilt isn't completely worthless but I am debating on taking it apart to salvage a little less than $90 in down and starting over. It wasn't a complete fail, I learned alot about what not to do on my next quilt.
The fact that the .34 cuben softens up after some use isn't a bad thing, that might make it feel a little better against the skin. I really need to find out about the durability of the .34. I read on the zpacks website that a very brave and gentle person could make a tarp out of .34 oz cuben. I feel like if that statement could be made then it should handle the shell of a quilt.
