Classic Thermal Merino Base Layer Crew – Kids'

For cold hikes, ski days, and chilly mornings on the trail, the Classic Thermal Crew is our go-to base layer for active kids. Merino wool regulates temperature, wicks sweat, and fights odor without synthetics, while flatlock seams stay flat against the skin to prevent chafing.

• 100% responsibly sourced merino wool regulates temperature, wicks moisture, and resists odor naturally, so it stays fresh through multi-day trips and back-to-back school days.
• Classic Thermal weight is built for roughly 25–50°F, which covers most Southeast winter hikes, cold-morning runs, and ski trips.
• Slim, body-following fit layers cleanly under midlayers and shells without bunching or riding up when kids are moving hard.
• Flatlock seams sit flat against the skin to cut down on chafing, which matters for kids who won't mention a problem until it's already a big one.
• Sizes XXS–XL in solid colors like Black and Rosewood Heather, plus prints like Black Tie Dye, Indigo Linear Peaks, and Winter Sky Animals.
