The Women's Sport Seamless Strappy Bra by Smartwool is an all-round comfortable companion for yoga, in the gym or on your walking tour. It has a seamless knitted inner made from a blend of merino wool, Tencel and polyamide and a supportive outer made from stretchy polyamide. The inside is soft against the skin and wicks away moisture. On the outside, the pre-shaped cups and wide underbust band provide support. The cups have removable pads. The narrow tank tops crossed at the back provide the right amount of support without constricting and allow plenty of air to reach the skin so you don't sweat too quickly.
