I've had my bivy since Jan 05 and have used it pretty steady year-round guiding since then. It's roomy and very comfortable to fit anything I need to keep close. I'm small (5'2 130lbs) so can get fully dressed in snow gear in the bivy if needs be. Only thing is I wish I'd seam-sealed it right away. Since I did it after 3 years it pulled all the seam tape off and made a mess. But I'm still dry sleeping out in the rain or snow with rare waterproofing treatment.
