Well, I've been doing some research all night about this but I still feel ambiguous about buying a bivy.
They seem durable, light-weight, comfortable, waterproof, and all that. However, how well do they really get the job done at higher altitudes/snowstorms/climbing trips/etc?
My main concern is how do you get in without getting the inside soaked during a snowstorm or rain? How do you fit your pack and what do you do with your wet clothes and boots?
Would it be reasonable to have a bivy as your main shelter for climbing trips?
Also, what kind of sleeping bag should I get along with a bivy? (I'm looking at the Outdoor Research Alpine Bivy). Is a +10 bag suitable for most weather you get in the Sierra Nevada's for example? Or would a 0 or -10 be better?
I appreciate the help guys. I'm just a really picky shopper..
