About the brand

Founded in 1974, Marmot has spent fifty years building expedition-tested gear — the kind that has summited Everest and weathered Antarctic winters — earning a reputation for bombproof waterproofing and warm, reliable down. At Mountain Sports, we love Marmot because it brings that genuine mountain pedigree to everyday layers: the same NanoPro™ shells and PrimaLoft® insulation that perform on the peak keep you dry and warm on the trail and around town.

The recycled nylon shell blocks wind, but untreated down should stay dry — not a hardshell.

Best for

Is this right for you?

Lightweight everyday warmth

A 700-fill down blend packs lots of warmth for its weight, with a relaxed collarless shacket cut that's easy to throw on for cool days around town.

Not for: Wet conditions — down loses loft when soaked, and this isn't a waterproof shell. Need waterproof? Shop Marmot shells

Layering and travel

Compressible down and a clean, collarless silhouette make this a versatile midlayer or standalone piece for travel and everyday wear.

Not for: High-output efforts — down runs warm and isn't very breathable. Shop all Marmot
