Smarty Pants Underwear gives you a smooth, sleek look under clothing. Designed to solve the problems presented by conventional underwear, these ladies' underpants are ideal with snugly-fitting breeches. A non-binding, chafe-free design with flatlock seams make them comfortable for riding and great for cross-training. The lightweight four-way stretch fabric wicks moisture and dries quickly to keep you comfortable regardless of temperature or activity level. Move freely and these underpants won't restrict or creep up. An antimicrobial feature resists bacteria and odor.XS(2-4), S(6-8), M(8-10), L(12-14).Machine wash cold, tumble or line dry.USA.
