Best for summer camping (Review by Dina)

I love this Bivy. Plenty of room and easy to get in and out. The floor managed to keep dry on wet ground. And the netting kept the mosquitos out. And the entire thing folds up nicely in my pack

Quality bug zapper (Review by BillD)

The OR Bug Bivy is the summer solution I’ve been looking for. Tucked into this baby with a tarp over it and you’ve got the best of all worlds, a view, a breeze, and a bug free night. I’m 6’ and 175 lbs and it feels pretty roomy inside, enough room for me to get dressed/undressed in, which is pretty roomy for a bivy. One time I must have had my knee pressed against the side netting while sleeping and woke up to 5 bites in the space of a nickel on my knee, other than that it’s been great. There’s lots of headroom, enough to keep the netting well off of your face. I've had no problems with the delrin hoop falling over. Peaceful easy sleeping for one pound, well worth it, although I'd gladly carry another few ounces for a solution to keep the lower part of the bivy off your body. Since you're probably using this when it's hot most people won't be wearing much under the net so another hoop or even just a sewn loop you could tie up to something would be a help in that department. Overall, it's well made and I'd definitely recommend it to anyone looking for a lightweight bug free hot weather solution.

Bug Bivy (Review by By Cougar Bait)

I use my Bug Bivy 4-5 days a week, working on a trail crew. Both for work and pleasure this bivy hasn't let me down. You will barley notice it in your pack. Its great to keep the creepy crawlers out and to throw in your daypack when headed into mosquito country, to have lunch in. This along with a tarp is the ultimate lightweight setup for spring and summer camping. The only trouble i've encountered is getting in and out of with ease, for those mid-night nature calls it can be difficult to shimmy out of, but what bivy is. Overall, this is ideal for simple, minimal camping weather it's backcountry, frontcountry, or beach camping.

Bug Bivy (Review by By ConnieD)

I may have had one of the first made.I use my Outdoor Research Bug Bivy often.I have never worn out an Outdoor Research Bug Bivy. I have had three, over the past many years, only because two were stolen.I use it backpacking and horse packing.I often use it for sleeping cowboy-style: no tarp, no tent.On well-drained ground, I flop over and the bottom has kept the rain off and all my gear was inside and dry.Sturdy, easily wiped clean.Looks like brand new.
