Smartwool's 100% merino wool interlock knit crew top is made to wear as a shirt or as an under layer for added warmth. It features flatlock seams that eliminate chafing, and side panels for a tailored fit. Naturally odor-resistant and itch free, your kids will love these soft and comfy shirts. You can even wash them with the rest of your clothes. So, that must be why they call it Smartwool.
