You're one of those people who tends to run cold, and nothing can ruin your day at the resort faster than becoming chilled. Once you have your lift pass, the Marmot Shussing Featherless Jacket is your ticket to a fun day on the slopes. This jacket keeps you dry and warm thanks to its MemBrain that seals out snow and slush and its 3M Thinsulated Recycled Featherless Insulation. This synthetic material imitates down with loose-fill fibers that trap in air, making it warmer without weighing you down. It won't collapse if you happen to get it damp, but getting moisture past the elastic drawcord at the hem, adjustable cuffs, and helmet-compatible hood will be a challenge.
