What Is 3M™ Thinsulate™ Insulation?
3M™ Thinsulate™ is a high-performance insulation material developed to deliver warmth without bulk. Unlike traditional down, which loses much of its insulating power when wet, Thinsulate™ maintains over 80% of its warmth even in damp conditions. Its ultra-fine fibers—just 2–10 microns in diameter—create a dense but breathable structure that traps heat while allowing moisture vapor to escape. Lightweight, compressible, and durable, Thinsulate™ is engineered specifically for active cold-weather applications like snow gear.
Built for the Demands of Snow Sports
In snow gear, reliable insulation is everything. Thinsulate™ stands out for its ability to keep warmth in and moisture out. Thanks to its hydrophobic fibers and multilayer structure, it doesn’t collapse when wet and continues to perform in harsh, variable mountain weather. Whether you’re carving through powder, hiking to a ridge, or riding lifts in freezing fog, it helps you stay warm without overheating or feeling weighed down.
Light but Durable in Motion
One of the most notable advantages of Thinsulate™ is its warmth-to-weight ratio. Compared to down, it delivers equivalent insulation with less volume and about 20% less weight. That reduction makes a difference in motion-heavy activities like skiing or snowboarding, where range of motion and reduced fatigue are key. It also recovers loft quickly after compression—ideal for gear that gets stuffed, sat on, or layered under packs
throughout the day.
Comfort That Lasts Through Conditions
Thinsulate™ isn’t just technical—it’s wearable. The material is soft, hypoallergenic, and free of animal products, making it suitable for sensitive skin. It resists clumping, wrinkling, and degradation even after repeated machine washing, offering long-term performance without the maintenance needs of traditional down. For riders and athletes who need their gear to perform day after day, this translates into less worry and more focus on the ride.
