EASY CARE

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

machine-washable-merino.svg

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.

Made for giggles, snow days, and every outdoor adventure — these warm kids thermal pants bring the cozy to all their cold-weather fun. Crafted from 100% pure Merino wool, they’re unbelievably soft, never itchy, and designed to keep little explorers toasty from sunrise sledding to sunset snowball fights.

The super stretchy waistband moves gently with them — no pinching, no digging, just comfort that lets them run wild and free. Naturally breathable and moisture-wicking, they stay warm without overheating, so playtime lasts as long as the smiles do.

And when the day’s done? Toss them in the washer and dryer. Built with quality to be handed down and loved again, these are the pants that make childhood memories warm, cozy, and full of heart. ❤️
