The Mons Royale Proximity Merino Sports Bra pairs a wide underband with cross-back straps to hold everything in place. That high-support structure stays steady from a strength session to a summit trail, and this merino wool sports bra stays soft against the skin the whole way. What Our Gearhead(R) Experts Are Saying:"By the last set, the fabric had dried out, so the band held the same way it did in the warm-up. The seams lie flat along that band, so nothing rubbed, and I never stopped to adjust."
