The Marmot Girls' Mobility Short is an athletic short for gym class. The brightly colored Mobility Short finally makes it more fun to change in the locker room for gym, with an elastic waist that is easy to pull on and stays up during all sorts of sports. The UPF 30 factor protects her from sun rays in spring and summer. The fabric wicks moisture away from her skin and dries quickly, the inside features a brief with Coolmax Gusset Liner for comfort while running and stretching. An interior key pocket secures her house key when she’s out playing with friends.
