Great! Tent!wrote a review of Black Diamond Lightsabre Bivy Sack on October 31, 2007
I spent 4 nights in a very humid place with this tent. Temps reached about 60 at night so it was hot and muggy. I got 0 condensation on the inside. I've used the previous version of this tent (the one without the foot vent) and thought it was very difficult to manage the dampness inside. The new foot vent was amazing and provided air flow that was much needed. It also allowed the material to be off my legs and feet when sleeping outside my bag because of the temps. The older style created a lot of heat inside against your skin because the tent material wasn't supported at the foot. I also found it to be great in the rain as the older style seemed to puddle up between my legs on the outside of tent. Then, this would create cold/hot spots leading to excessive condensation. Overall, an outstanding buy. Provides tarp like qulities, yet comfort of a tent.
