Classic Thermal Merino Mock Neck - Women's

What Our Gearhead® Experts Are Saying:

"This mock neck has become my go-to for cold-weather layering. The 100% merino wool keeps me warm and dry, even when I'm breaking a sweat on the skintrack or hiking in the snow. I especially appreciate the chafe-free seams and the longer back hem—it’s warm, breathable, and super soft."

We rely on the Classic Thermal Merino Mock Neck for everything from dawn patrol tours to fireside lounging after a long winter hike. Smartwool crafted this base layer with 100% merino wool, delivering natural odor resistance, breathable warmth, and unbeatable comfort directly against the skin. The mock neck design adds just enough coverage to block out biting cold while keeping the silhouette streamlined under outer layers.

This piece is engineered for performance with flatlock seams to reduce chafing, set-in sleeves for natural mobility, and side seams that wrap forward to eliminate bulk and enhance the fit. Whether we're headed out for a powder day or layering up for chilly travel days, this thermal essential moves with us and keeps us warm no matter where we roam.
