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.

How it ranks across conditions.
Calibrated against comparable products we stock, so you can compare like for like.
Is this right for you?
Long, sunny trail days
UPF 50 and a breathable knit keep you cool and protected through hours of exposed miles, from thru-hikes to marathon training.
Not for: Cold or wet weather that needs insulation or a waterproof shell — this is a warm-weather sun layer. Need warmth? Shop Marmot layers
Hot-weather running and hiking
Sweat-wicking fabric and raglan sleeves move with you, dry fast, and won't overheat when temps climb.
Not for: High-wind or chilly starts — layer a shell or midlayer over it. Shop all Marmot
All-day sun coverage
Thumbholes and long sleeves extend protection to the backs of your hands for gardening, paddling, or travel in strong sun.
Not for: Peak-heat efforts where a short sleeve or tank breathes better. Prefer short sleeves? Shop the Windridge SS
