On a recent , Feb 2018, cold and windy stay at the AT's Walnut Mountain Shelter (the nastiest Shelter I've been too, with apple cores all around and garbage everywhere), the mice came out to play. Fortunately for me, I brought this net (along with another brand's 8 ounce, 5.5'x9' tarp, when outside of a shelter). I only used the head pole and did not even have to attach the loops for clearance or do some creative staking around the wood. It kept me away from the crawlers and it takes very little space in a shelter. Even better was the fact that it kept my quilt edges in place, preventing them from lifting in such a strong wind plus the mesh kind of slows down the wind. This is a great option from going shelter to shelter! The only reason I did not give it 5 stars is that it would be great if this was part of a two stage system, instead of having to buy one of OR's other bivy sacks. How much more to sell such a bivy with a cover, some hook points and some sort of ventilation at the feet, like a 2 layer tent? Additionally, the bathtub design is better around the head's side than south of the zipper. Finally, it would be a little bit easier to get in and out if the zipper design extended to run along the lower sides partially. Again, this is wishful thinking and I'm extending the mission of this bivy, but, as stated above, I have a painful-to-set-up-when-you-are-tired-at-the-end-of-the-day tarp addition when a Shelter is not available.
