EASY CARE

Follow these tips for the best performance and longest life for your garment:

Machine wash cold inside out and Tumble dry low.

Avoid fabric softener. Though it won't damage the clothing it does coat the fibers in a wax that neutralizes many benefits of Merino.

Cold days don’t stand a chance. These children’s wool thermal bottoms are made for warmth that lasts — soft, stretchy, and crafted from 100% pure Merino wool. They keep little legs cozy and dry through every snowflake, sled ride, and outdoor adventure.

The gentle, flexible waistband never digs or squeezes, giving all-day comfort that moves with every laugh, jump, and tumble. Naturally breathable and moisture-wicking, these bottoms keep them perfectly warm without overheating.

Machine washable, heirloom quality, and made with a whole lot of heart — these are the cozy essentials you’ll hand down with pride.

Style #X821

These bottoms are a regular, baselayer fit. We recommend purchasing normal size.
