This is a perfect-for-anything-but-winter jacket. Love the stretchy mobility when navigating scree slopes looking for marmots. Layers well and does fine as an outer layer in all but the worst conditions. Stylish enough for around town too. Typical great Marmot quality.
Bought this shell for running and use during the fall and spring and i love it. Jacket adjusts great to a large array of temperatures and conditions. The only problem i have with it is the sizing, i'm 5'10" 175lbs and i got a large, it fits well however there's a lot of extra space in the gut, overall though this is a great product.
