Luke S.wrote a review of Black Diamond Spotlight Bivy on May 4, 2010
This is a great bivy. To start this packs oh so nice and small and I can through it in any pack that I would do an overnight trip with.
Setup becomes a breeze after about your first handful of times. The first time I set it up it took about 10 min. of trying everything to get the pole in. A tight fit to say the least. Now I know how to position it and can do the entire thing in about two minutes. Packing it away is just as easy. The longest thing to do is push the air out of it while getting it into the stuff sack.
This is a little bit snug with my pad (Big Agnes Air Core), bag, and myself in there but what you would expect from a bivy at these dimensions. I had plenty of room to keep a rain jacket, clothes I hiked in, and boots above my head. A pack probably won't fit. At 5'9" I can get in and out with ease. The ventilation is good at night as long as you leave it cracked in the right places. I just had it out on a trip that started with very high humidity and led to heavy rain. Never had a problem with condensation build up on the inside. It doesn't come seam sealed and I haven't done so yet. It held up very well in a down poor that lasted about an hour with no moisture on the inside. Going to seam seal it however to avoid pushing my luck.
Overall an excellent bivy and misses on five stars because I have to seam seal it myself and a little difficult to setup out of the packaging.
