I"ll second wiggys. Just got a sleep system from them for my cold natured wife and she was extremely warm in the 0 bag. And we can put the outer bag on if needed to protect down below zero. Works when wet. ITs not the lightest but they compress well in their own stuff sacks. Walk ins to the store get a discount so if you internet them -- see if you can find someone in CO to buy it for you.

Worth the money for us.
