I am 5'8" weighing 146 pounds. Med/Large/ExLarge fits well over long sleeve base layer. I purchased gray. This is a sporty multiplayer. The shape allows it drape loosely or gathered close for warmer effect. Too early to evaluate durability. I am a knitter, however, have never knitted with this fiber. Seems very delicate. I am hoping to wear everyday as an outer layer late November thru February. May be too delicate for camping. It is beautiful and the design is sporty elegant. I purchased to reduce my cardiac arrhythmia triggered by cold. Arizona Summer's offer outdoor temps of 110+, indoor shopping 68. I will probably trial the sweater this summer while grocery shopping.
