GTwrote a review of Black Diamond Tripod Bivy Bag on August 10, 2006
Much, much better actually. No more claustrophobic steamy nights in a tube bivy. Like other Bibler tents, it is tough as nails, exceptionally water proof and made to the highest standard. I spent several nights in it in some of the worst thunderstorms the Unitah and Wasatch mountains had to dish out - hale, rain, and freezing night time temps, and it worked extremely well. The vestibule at the top gives you a glimpse of the outside, is perfect for keeping your boots dry, some water and snacks, and even allows reading with a headlamp.
