By hunter/riverguide from NE Oregon on 10/05/2009 Pros: Comfortable, Easy to pack Describe Yourself: Outdoor Professional Bottom Line: No, I would not recommend this to a friend Comments: I used it this weekend in Hell's Canyon during heavy rain. i went to bed damp and woke wet. Too much condensation, and no evidence of breathing.
Meets my "works in real life" test By Bill from Worcester, MA on 10/02/2009 Pros: Comfortable, Compact, Easy to pack, Lightweight Best Uses: Backcountry Camping, Survival Describe Yourself: Avid Adventurer What Is Your Gear Style: Minimalist Bottom Line: Yes, I would recommend this to a friend Comments: I use this bivy as my main form of shelter on trips. The bag is long with extra length (over my 6' body) to hold my boots, headlight, phone and assorted clothing items. The bag is plenty wide for the above items, my mummy bag and a wide EMS sleeping pad. I used it in a light rain twice and the second time the foot box of my sleeping bag got wet...not just condensation. Later, I used Kiwi waterproofing spray and slept in a steady drizzle and the entire bag was dry. I am now happy with the bivy and how easy it is to use in thick woods where a tent would never fit.
The way I use this bag helps keep me dry. I put a poncho on the ground to protect the bag from general grime and wetness. I then sleep with the bivy completely zipped except for about 4" for my nose and mouth to "stick out". If it is raining I modify the opening so that the lower portion of the opening is under the side of my face and the upper part sort of hangs over the top side of my face creating a little "porch" for my face and preventing rain from hitting my face. If it really comes down (rain,) I just back my head from the opening a bit. Using this method I only get very slight inside condensation in humid weather and I can "pump" the bag open and closed with my legs to get fresh air into the bivy if needed. Using the bivy in this way makes set up and decamp very fast, which is necessary to stay dry when it is raining.
By DanTheDevil from Soda Springs, CA on 09/28/2009 Pros: Compact, Lightweight Best Uses: Backcountry Camping, Winter Conditions Describe Yourself: Avid Adventurer What Is Your Gear Style: Minimalist Bottom Line: Yes, I would recommend this to a friend Comments: From the once-over in the livingroom... nice, well made piece that will fit into multiple sleeping systems. Smaller/lighter than my old bivy sack.
