The Wander Bra is a performance sports bra built from Activist Treemerino, a light terry fabric blending 60% super-fine 19.3-micron merino wool with 40% Tencel Lyocell. It provides light support with a slim fit, making it well-suited for climbing, skiing, and other active pursuits where a comfortable base layer matters. The merino wool delivers natural odor resistance and retains warmth even when wet, while the Tencel adds softness and moisture-wicking properties. Both fibers are renewable and fully biodegradable, and the garment is designed to be returned for recycling or composting at end of life.
