Layering properly for a day in the mountains is a fine art that very few have mastered. Luckily, Scott's Men's Insuloft 3M Down Vest makes the mystery a little easier. Lightweight and packable, this vest is easy enough to throw on over a jacket when the winds are howling mid skin rip, and the Thinsulate insulation provides toasty warmth without added bulk. Plus, zippered hand pockets are the perfect spot to stash a candy bar for a pick-me-up along the skinner.
