I am looking for a bivi sack. I did a search and looked at the posts. I have decided I am looking for a bivi sack with bug netting, some kind of wire to keep the fabric off the face and will close up so that your face is not exposed to the wind/weather. I have several gift cards to REI and the dividend so I am going to limit my choices to what REI sells. The two choices are both ID bags. First the EVENT Bugaboo, and then the EVENT UniShelter. I would go for the Bugaboo but the center zip idea seems suspect to me. Has anybody had any experience with this (don't plan on using in rain). I am 6 ft. 5 in. so the length on both seems ok. Also the bugaboo is lighter than the unishelter. It is just the center zip that has me worried about getting into and out of the bag as well if it does sprinkle what the leakage would be like.
Thanks for your help.
