Sierra Appalachian Mountaineering Jacket (4 Designs)

Durable, water-resistant, and stylish - that’s the best way to describe a Sierra Appalachian Mountaineering Jacket. Our waterproof and durable outer coating turns away rain, sleet, snow, or hail.

All of our jackets feature our proprietary MAMX™ insulation technology that will keep you warm even when the mercury drops faster than a slope in Colorado. Our extremely breathable material features a special coating that consists of a tri-component, multi-layer formula that promotes moisture permeability and durability.

Optimal interior comfort is ensured by our thermal fabric so you don’t have to choose between keeping warm and feeling good.

Odor Control

Come back from your next adventure smelling fresh. Sweat may be odorless, but the bacteria that it generates is not. Our interior fabric is designed to prevent the growth of odor-causing particles so you can explore more and clean less.

Care

Machine wash warm using mild detergent.

Tumble dry low.

Do not use bleach or fabric softeners.
