User Review: Outdoor Research Advanced Bivy
Design: body bag
Ease of Setup: one handed blind
Weight: 2 lbs
Price Paid: $179 (in 1995)
I've used this bivy for eight years, probably spent at least 130 nights in it. It is a testament to the design that OR has not really changed anything on this sack since it came out in the early '90s. I've not ever had to repair it. It's kept my down bag dry in 2-day downpours and warm in the snow. Condensation isn't a problem if vented properly. I usually use a 4'x8' tarp over the head area. I can't say enough about this sack. If mine ever wears out I will buy another one even though the price has gone up considerably.
