Mjolnir Fleece-lined Merino Technical Beanie

When to use — Climbing, skiing, trekking, and alpinism. Close enough to wear under a helmet. Stylish enough to wear everyday.

Versus the Sinni — Where the Sinni is 100% pure merino for those who prioritise natural materials, the Mjolnir is a performance-focused blend. The acrylic content adds durability and shape retention; the microfleece lining adds a layer of warmth.

Internal microfleece band — Anti-pill fleece lining creates a warm, soft layer directly against the ears and forehead — the areas where heat loss is highest and where cold is felt first. Also prevents the knit from pilling against skin over repeated use.

Interlock knit — The construction creates small air pockets within the fabric that trap warm air — a more technical build than a standard knitted beanie, giving better insulation for the same profile.

Helmet-compatible fit — Close fit sits cleanly under a ski or climbing helmet.
