What Our Gearhead(R) Experts Are Saying:"I love how this jacket handles everything the mountains throw at me. The GORE-TEX(R) shell keeps me dry in heavy storms, and the insulated liner is super warm without being bulky. Whether I'm ripping laps at the resort or braving high winds on the summit, the 3-in-1 system is perfect for adapting to changing weather."Weather in the mountains can shift on a dime, and the Marmot KT Component 3-in-1 Jacket keeps us ready for anything. Built with GORE-TEX(R) 2-layer waterproof technology and fully seam-taped construction, the shell shields us from unexpected storms and biting winds. When temperatures drop, we zip in the Thermal R insulated liner, designed with Pertex Quantum(R) fabric to trap heat and block out the chill without restricting our movement. This jacket is our go-to for versatility, whether we're lapping the lifts, hiking into the backcountry, or grabbing post-ski beers in town. Thoughtful features like waterproof zippered pockets, a removable storm hood, and an adjustable fit make this 3-in-1 system the ultimate layering piece for unpredictable winter days.
