Outdoor Research Helium Bivy for stealth alpine camping

Durability for the 2.5 layer Pertex will be poor. I have heard that sleeping in a bivy actually creates a lot of abrasion on the inner fabric layer, so this would not be good. I would search for a 3 layer option.

Rab and Integral Designs (pretty much the same company) also offer a lot of their bivies in an olive color.

Jeff,
if you can't sleep in it, what are you supposed to do with it anyway?

I’ve had my eye on a Locus gear event bivy in black.

Don't sleep on the Borah event bivy, John does great work at a fair price, and custom work is priced low.

Having actively used my Helium 2 jacket over the last year, I wouldn't want to sleep in a bivy made of the same material. The breathability is not the best.

I'll also second the BG eVent bivy however. For a little more money I had him add a cuben floor instead of the 70D which helped shed a few more ounces, if that type of thing is important to you. It's a monstrous size, I'm 6'4" and swim in it so you could probably request smaller dimensions and save even more weight/pack space.

Unless you use the bivy a ton, durability would be fine. Nothing compared to the beating a fabric gets under packstraps. I would assume breathability would be less than ideal, especially if you're all zipped up, but every better option will cost a lot more. You'd do just fine in a light rainstorm, though a green or brown tarp pitched super low might be a better choice. And cheaper, too.
