Thermal Grizzly Men's Thermo Wool Thermal Sweatshirt - Merino Blend Base Layer, Round Neck, Long Sleeve, Seamless, Athletic Fit

When winter bites, layering becomes a science. A base layer that traps heat but also breathes is the difference between a good day outdoors and a miserable one. The Thermal Grizzly Men's Thermal Sweatshirt Thermo Wool solves that equation with a merino-rich knit that regulates temperature, wicks sweat, and fights odor—so you stay dry, warm, and focused from first chair to final descent.

Who is it for

Built for men who train and explore in cold conditions: skiers, hikers, runners, and anyone who needs reliable warmth without bulk. The body-hugging athletic fit and 4-way stretch move with you through dynamic movement, while the seamless two-layer knit eliminates chafing during high-output activity.
