"OK for quick and light" - Review of Black Diamond Lightsabre Bivy Sack

I used this bivy for a 5 day backpacking trip through the Sierra Nevadas and I am now looking for something more rugged. Its great if you are looking for sheer lightness and summertime use. I am only 5'3" and it was hard for me to get in & out of because of the short zipper and head overhang, I'm sure it would be even tougher for a tall man. It was waterproof (though I had to seamseal all seams myself). My other complaint is there was a ton of condensation on the inside of the bivy in the a.m. (even with the front wide open during sleep).
