The Mountain Hoody is the new king of warm-ups and cooldowns, from crag-side to pre- and post-workout strides. Make sure your name is sharpied on the collar because your workout partner (or your girlfriend) might try to pull a fast one and claim it as their own. Yeah—it's that comfy. A lightweight, jersey-soft polyester and cotton blend means it can perform in the wild but retains a lush sweatshirt feel for more tame everyday use.
