Bests & Worsts Reviews from Amazon

I have a regular bivy but rarely use it as my tent is only 24 ozs. I picked this up as a light weight way to crank up warmth of a lighter bag and to carry on extreme day hikes (just in case). I am 6-1 188 lbs and I fit in this bivy in street clothes. I also found that I could use my Mountain Hardwear Lamina 45 inside. Not constricted, but not much extra room. Also at 40 degrees it was way too hot inside. The draw cords allow the hood and shoulder openings to be closed to the "nose only" position. This was designed for emergency use, but with care I believe multiple uses are not out of it's abilities. Breathable; we hear that a lot and basicly it means something breathes better than Saran Wrap or shrink wrap. If you zip and cinch this bivy up there will probably be moisture inside. Depends on temps and humidity. I like the zipper, although I would prefer it 1/2 length instead of 24 inches. It gives easy venting possibilities to help control inside temp and moisture biuldup. Also much easier to enter/exit. Actual weight bivy 8.4 oz 239g stuff sack 0.2 oz 7g I like this bivy and would recommend it. Will try to post some pictures. If you don't care about the zipper and want lighter weight see SOL Escape Lite(tm) Bivvy weighs in at only 5.5 oz.
