Optimized to meet trail running’s high output demands, the Motus is patterned for exceptional freedom of movement. The women’s specific trim fit and stretch fabric move with the body and keep the fibres close to the skin to maximize wicking performance. Reflective blades at the sleeves increase visibility in low light.
