I'm in the market for a puffy coat, but I've never been very good at layering. I'm always too hot or too cold. I'm rather new to winter activities, and I think I've settles on the Micro Puff. But I can't decide between a Med or Large. The Medium fit well over a base layer and a light fleece with room to move comfortably. But would I get more use out of going to the Large so I can fit it over more layers if need be?
I prolly won't be backpacking in anything under 15 degrees, but for general backpacking, skiing, snowshoeing.. is the Micro overkill? Should I go for the Nano? And what size would you recommend?
