Great First Run
Took this out during my last Sierra's Trip, and was extremely happy with it overall. Very roomy, much more so than the sleeping bag I used with it for the first climb. Took a 30 degree bag up Mt. Whitney, along with this bivy, and slept at 12,000 ft. and was toasty warm. The pole was nice and provided ample head room. Unzipped the top a little and had no problems with condesation. Only one problem: It only opens 180 degrees around the head portion of the bag, making it a little difficult to get into and out of quickly. Otherwise, an outstanding lightweight shelter.

i got this bivy used (but in perfect condition) and have used it for over 200 nights in rain, snow, wind, etc. i haven't been in the mountains with it for over 200 nights but this was my home for a few months as i slept on my friends apartment deck while looking for a place to live. everywhere it's gone (baker, shuksan, rainier, hood, etc.) it has performed very well. even in an all out winter storm this bivy held up to the elements... especially wind.

the optional pole is great if you want to be comfortable. the pole barely weighs anything and if you're willing to lug this thing around, the pole shouldn't be too much of an added burden. but then again, i'll leave it at home sometimes to get the illusion that i'm going light.

the weight of this bivy is a bit more than most, but it is also indestructible. it's bittersweet... it'll handle anything and hurt your back.

because of the weight i generally use this on bigger mountain where a good bivy could be a life saver. for smaller fast a light summer trips, i would never even consider taking this... too heavy.

In the end, i'll continue to use this when the conditions call for it and love the headroom the pole offers.
