Classic Thermal Merino Base Layer Crew – Kids'

Built for cold-weather days on the trail, the mountain, or the ski hill, this merino crew is our top base layer pick for active kids. 100% responsibly sourced merino wool naturally regulates temperature, wicks moisture, and fights odor without any synthetic help. A slim, flatlock-seamed construction sits close to the skin and layers cleanly under anything.

• 100% responsibly sourced merino wool delivers natural warmth, breathability, and built-in odor resistance — no synthetic additives needed
• Classic Thermal weight hits the sweet spot for cold-weather layering, roughly 25–50°F, making it the right call for winter hikes, ski days, and cold morning trail runs
• Slim, body-following fit layers cleanly under midlayers and shells without bunching or riding up during high-output activity
• Flatlock seam construction sits flat against the skin to minimize chafing during all-day wear — especially important for kids who won't tell you something's wrong until it's already a problem
• Available in a wide range of colors and sizes (XXS–XL), from solid Black and Rosewood Heather to fun prints like Black Tie Dye, Indigo Linear Peaks, and Winter Sky Animals
