I'm normally a tent guy. This bivy has all the pluses of a tent and no negative. Packs as small as my first. But im totally enclosed. Used my handle bars to lash it up in front. Enough space to put my clothes next to me when i slept. And Im 6'3" 230lbs . No moisture build up. Highly recommend. Worth the price. My first trip with this was the stagecoach 400. So it had a good test
I like it.
The biggest appeal for me for this product is the zipper. I had another bivy that required you to shimmy into an opening messing up your sleeping pad and bag. The second biggest appeal was the mesh upper. I've found the full on water proof bivy's keep moisture out but also keep it in. The open design allows the system to breath and kept me comfortable. My first use was in the snow with a low around 15F and a hi around 40. With a tarp over top similar to the video on the website and some other gear I was more than comfortable. If you're a big guy or gal ibr commend the larger size. A little more comfortable with no size different in terms of packing it up. That's the other great part. There is no folding, finicking, or fussing getting this to pack. It could fit in a jacket pocket if you wanted. The reason I gave it four stars is just because it's not water proof. Otherwise it's absolutely fantastic.
