Why choose between a shell that breathes and one that stays warm on the chair? This jacket handles both, with a light, soft lining across the back and sides where the wind bites hardest, and underarm vents to expel heat when you're sidestepping to a hidden stash. It's tough enough for storm laps and tree runs, with a regular fit that leaves room for a midlayer on colder days. Ideal for wind-whipped days at Castle Mountain, where the ridge hikes are sweaty and the chairlifts are anything but.
