Smartwool Kids' Classic Thermal Merino Wool Base Layer — Bottom (Slim Fit)

Our Kids' Base Layer Bottom is crafted from 100% Merino Wool, offering a super-soft, interlocking knit perfect for layering in cool conditions or wearing alone on a mild day. Now your kids can experience the same warmth, dryness, and comfort as you do in your Smartwool base layers.

Designed to meet the demands of outdoor adventuring, these slim-fit bottoms rest easily under layers while providing unrestricted movement through the legs. With a 20-inch inseam, the classic thermal Merino construction is ideal for cold-weather activities where warmth and breathability are crucial. The midweight fabric utilizes a 100% Merino wool build that helps move moisture away from the skin, keeping them warm and dry.

Thoughtful features ensure your kids can go far and feel good. The interlock knitting enhances breathability, thermoregulation, and moisture-wicking, while flatlock seams minimize chafing for greater comfort. From wool socks to base layers for men, women, and kids, Smartwool is committed to providing the highest quality apparel for your outdoor adventures, with a focus on environmental sustainability, racial equity, and inclusivity.
