I went Spring camping in the Appalachian Mountains recently, using the Patrol Shelter, the Soul Bivy, and the XP 21 oz. quilt. The weather forecast called for light rain. Naturally, the rain was torrential, with heavy winds of up to approximately 40 miles an hour.
The Soul Bivy (size large, 7.5 ounces), despite the high humidity, had very little moisture on the outside: just a few drops. The quilt was dry. The Momentum fabric on the top is, as advertised, quite breathable.
For me one of the clever and attractive features of this Bivy are the cords to attach both an internal and external sleeping pad. I put a closed cell foam pad underneath the bivy, eliminating the need for a ground cloth. I used a BPL Torsolite self inflating pad on the inside. The cords keep both pads stable.
I have not discussed the product specifics here because they are fully described on the Mountain Laurel Designs web page. The take-home message is: Another very well-made Ron Bell product-- light, well-made and easy to use.
