Smartwool, a merino wool performance apparel brand, has launched its Autumn/Winter 2025 Collection.

Designed for runners, hikers, skiers, and everyone who chases joy in the outdoors, the new collection blends natural Merino performance with body-enhancing fits and bold design.

The Winter Run offering features Merino-powered essentials including Cold Weather Run Socks, Active Fleece, Active Fleece Wind, and SmartloftTM insulation. Each piece is engineered to keep runners warm, dry, and moving with confidence through the coldest, wettest conditions.

For those who embrace the outdoors year-round, Smartwool introduces All Season Base Layers and its latest Hike Socks, delivering versatile, breathable comfort that adapts effortlessly to shifting temperatures and terrain.

Drawing on its deep snowsports heritage, Smartwool continues to elevate mountain performance with beloved staples like the Classic Thermal Base Layer and Ski & Snow Socks, now joined by new SmartloftTM pieces built for long days on the slopes.

This season, Smartwool also introduces limited-edition collaborations with iconic artists and athletes, including Arbor x Bryan Iguchi and an Open Hearts Collection by Chris Benchetler.

At the core of Smartwool’s sustainability mission, the award-winning Second CutTM Collection makes its return. Featuring fleece and slippers crafted with up to 75% upcycled materials, this line proves that premium warmth and responsible design can go hand in hand.

The IntraknitTM collection gets a performance upgrade with 3D-knit Thermal Base Layers and Ski/Snow Socks, providing seamless comfort, mapped ventilation, and elite backcountry performance.
