A tunicwith the power to keep us warm without bulk, the power to wick us dry, the power to stay odor-free and itch-free. That's the power of Smartwool mid-weight Merino. Wear it alone when it's cool, layer it over long janes when it's cold, you choose. Only @ T9. XS(2), S(4-6), M(8-10), L(12-14), XL(16).
