Clean, smart design and intelligent fabric technologies combine in a performance top for fast-paced, warm weather mountain training. The Arc'teryx Women's Phase SL Long Sleeve Zip Neck is made of Phasic SL, an advanced bi-component fabric that wicks moisture and dries quickly.
Designed for high-output mountain training, the top is anatomically patterned and has gusseted underarms for exceptional freedom of movement. The women-specific trim fit moves with your body and keeps the fabric close to your skin to maximise wicking and performance. Reflective blades at the sleeves increase visibility in low light.
