Yea its always nice to be in a bivy in -25 degree weather with snow as I did one deer/elk season in MT. Believe me it's not fun when you get snow and you are in a bivy. Then when you want to get out and put your boots on and it is pouring rain or snowing it is even more fun. But to each is own.
What do you do with your packs when it rains? Why not just use a pyramid type shelter and be done with it, rather than carrying a bivy that's stuffed size is 15 x 4 inches and then carrying a tarp on top of that?
