Smartwool, a leader in merino wool performance apparel, is proud to introduce its Fall/Winter 2025 Collection, a bold, comfort-driven lineup built for those who thrive in every season. 

With a renewed focus on circularity, inclusive design and performance-driven innovation, this collection empowers adventurers to go farther, feel better, and stay outside longer, no matter the forecast.

At the heart of the FW25 collection is Smartwool’s commitment to comfort, confidence, and community. Designed for runners, hikers, skiers, and everyone who chases joy in the outdoors, the new lineup blends natural Merino performance with body-enhancing fits and bold design.

Collection Highlights

The Winter Run offering features Merino-powered essentials including Cold Weather Run Socks, Active Fleece, Active Fleece Wind, and Smartloft 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 Smartloft™ 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.
