Choosing a bra to wear on a multi-day hike is no small matter: comfort, support, and odor-fighting become even more important after a few nights in a tent. You may not ever ask it to make it for a marathon session, but the Icebreaker Sprite Racerback Sports Bra is ready if you do. With open racerback straps, this soft bra gives you medium support with maximum range of movement, hour after hour. A customer favorite.
