Peter G.wrote a review of Black Diamond Bipod Bivy on November 14, 2016
Familiarity: I returned this product before using it
Ever wondered how to die in a bivy bag? It's really simple, but here's the method I recommend: Do it in the Black Diamond Bipod bivy via these pathways:
1) Compress your insulation
The Bipod is not built for a high r-value pad and a high loft sleeping bag. I stuffed a Big Agnes Double Stuffed Double Z and a North Face Inferno -20 sleeping bag in this thing, crawled in, and found my feet pressing through my insulation to the bivy wall. The top layer of the bag is too tight and compresses the insulation against the body, too. Given the winter trips over 12k ft that I bought this bivy for, this is an absolute no-go.
2) Have a complex zipper system
The zippers over your head and where they land are crucial when you're stuffed into a frackin body bag. With a net zipper and a shell zipper, and multiple pulls on both, this sucka is insane to get in and out of. No cord pulls on the zippers with reflector cord... talk about a scary emergency exit.
3) Complex setup
Bivy bags are great for a couple situations. One of those is high wind, high altitude, low temperature camp outs without any princesses along. The pitch has to be fast, simple, and not requiring any fancy finger work or added frustration. Does this bivy accomplish that? Yea-nooo. This bivy comes with an idiotic cloth pole hole system that likes to pop out when you're trying to get the other side mounted. The pole doesn't come with any bullet tips, so it's like trying to feed a water pipe through a sock with one hand. Wanna do that in 60 mph winds while it's snowing? Nope.
Otherwise, this bivy is the closest thing I've seen on the market to a livable bivy. Aside from the foot box being too small, and without any box to it; and the stupendously wrong pole system, and the small volume, I had great hopes for this item. I would use it with a low loft pad and a thin 20 degree bag, but I'm afraid that this is not a piece of gear I will be trusting my life with in the conditions I intended it for. . Such great potential, but a very dangerous failure in design. The Bibler Tripod Bivy it takes after appears superior. It is sad to see this bivy fail. It is the only bivy on the market with a good entry and headroom. Three simple design changes and I'd buy two of these -- it's so close to being a solid piece of gear.
I'll be reutrning this one.
