SmartWool Midweight Underwear Crew - Kids'

Exclusive to REI, your favorite SmartWool long underwear is now available for your kids! This midweight crew for kids offers natural stretch and breathability for stop-and-go activities or when temperatures fluctuate. 100% super-fine merino SmartWool works to help maintain comfort whether the climate is warm, cold or in-between. Flatlock side seams prevent chafing. SmartWool is guaranteed not to itch and can be repeatedly washed and dried without shrinking. Easy care: machine wash and dry on cool temperature setting. Please note: product runs big to accommodate for growth and the 2 to 3% shrinkage in length during the first wash.
