Build yourself a great "action suit" - just add one or two light layers under this jacket and you're good to go. Or use it as a killer midlayer. Designed for cold, windy, dry-snow conditions, the Mountain Guide is windproof, water-resistant and highly breathable. Four-way stretch ensures you don't have to fight your gear while assaulting a grade V alpine wall. Two lower front pockets, one chest pocket. Machine wash. "Wear this as a breathable outer layer in windy and dry snow conditions. Doubles as a windproof midlayer to allow transition through changing temperature and weather." - Ed Viesturs
