This is a great bivy for most uses. However, it does get awful drafty through the mesh screen above your face. It would be great if there was an option to seal that off and prevent breeze from entering the bivy.
Just tested it out during 5 wet days in Denali NP. The bivy was exceptionally comfortable (I got the wide for a little extra space). It stayed pretty dry under a low slung tarp which did wet through (Condensation on a dry but damp night was not an issue), and it was also durable enough to deal with some light abrasion against brush willow. Definitely a fan.
On a recent trip to the Lake District in the UK weather conditions meant that there was a high level of cloud inversion that made my shelter damp [single skin tent]. I used the Bristlecone to cover my sleeping pad and quilt to prevent them getting damp + add some extra warmth.
I've used other sleeping bag covers but can honestly say the Bristlecone is far superior to any of them. The breathability meant that there was no condensation build up on my quilt and in the morning whilst the tent walls were running with condensation I was dry and warm. Fantastic item of kit that I won't be leaving at home on any trip!
