        This bivy is the best I have used yet. All other bivy's I have tried (6 different brands in the past 10 years) have all been either too narrow to allow reasonable movement while sleeping, or too claustrophobic, or too heavy, or all of the above. MSR got it right with this bivy. I am 6-1", weigh 240 lbs, and I have plenty of elbow room inside the bivy with it zipped up.... without feeling claustrophobic. The mosquito netting provides complete bug protection if needed in warmer weather. In cold weather the bivy adds about 10 degrees to your bags temp rating. I used this bivy recently on a 50 mile/four day hike in Los Padres National Forest in central CA (April 2011). We had rain, snow, freezing temps. I used the bivy with the Thermarest 35 deg alpine blanket and the MSR E Wing tarp shelter. I was toasty warm all night long, waking up to ice on the E wing tarp each morning. Very little condensation on the inside of the bivy. You just have to make sure you breath through the opening in the bivy, and not into the bivy itself. Very well designed, well thought out... I highly recommend it, and also recommend using the thermarest alpine blanket and the MSR Ewing tarp shelter.

          Best Uses

          • Minimalist backpacking

          I opened mine new bivy on the trail (yea, I didn't check it before leaving...) so when I was setting up for the night, I realized that inside my AC-Bivy bag was not an AC Bivy but and E-Bivy someone swapped to get an AC-Bivy for half price. Well, the E-Bivy has no zipper or screen and it was raining. With a little improvising, I managed fine. Worked like a charm; the rain just rolled right off and this little brother even protected my junk sleeping bag. Keeps in heat too! I'll review the AC-Bivy when it comes; REI CS took my E-Bivy back and is shipping me what I paid for. Excellent product.

          Best Uses

            Just too hard to get into and out of quickly/easily (and to ventilate) with the 'envelope' design. If it had a side zipper I'd give it 5 stars. As is, I'm going to return it and get the REI brand with the zipper.

              I took this bivy with me to Yosemite for a 5 day hike. With rain in the forecast, I also bought the MSR Tarp (a little spendy) but as a pair, they're a ultra-lite match for dryness. The tarp kept 99% of the rain at bay and the remaining had no effect on my Mountain Hardware Phantom 15 sitting roomy and cozy in the bivy along with my High Sierra Phantom 45+10 at my head (also covered and dry). Condensation as expected (mostly at the feet), but dried right up in the morning sun in about 15 minutes. Love this pair (bivy + tarp).
