Outdoor Research Highland Bivy

Condensation Problems
June 11, 2010

Hello, I ordered the highland bivy and set it up on the wet ground after a heavy rain for two days. Granted this setup was in extreme wet conditions but I still feel like it was a legit test. I got settled in for the night...which was clear skies, and after zipping up left about 8 x 4inches of ventilation gap in the zipper. I feel asleep but woke up off and on during the night with a damp feeling inside the bivy. It was dark so I didn't really know what was getting wet until morning. Dawns light revealed the problem. Even when providing enough ventilation, the highland bivy had major condensation problems and the morning light revealed very wet inside walls and a wet sleeping bag where ever the bag touched the walls of the bivy. Back to the drawing board Outdoor Research!
