SmartWool Midweight Long Underwear Bottoms - Kids'

Now available in kids' sizes, and exclusive to REI, SmartWool's warmest base layer is ideal for stop-and-go activities in cold weather. Super-fine Merino wool regulates warmth, wicks moisture away and repels outside moisture. Wool fiber's natural crimp traps air within fabric to keep you warm in cool conditions. Flatseam construction is soft and non-chafing next to skin. SmartWool is guaranteed not to itch and can be repeatedly laundered 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.
