Minimalist design and advanced fabric performance combine in a technical shirt for fast paced, warm weather mountain training. The Motus SS Crew is made of PhasicTM SL, an advanced bi component fabric that wicks moisture and dries quickly. Designed for dynamic movement of high output training, the Motus is anatomically patterned and has gusseted underarms for exceptional freedom of movement. The trim fit moves with the body and keeps the fabric close to the skin to maximize wicking and performance. Reflective blades at the sleeves increase visibility in low light. FABRIC FOR FUNCTION PhasicTM SL, an innovative Arc'teryx next to skin fabric, is a key to the Motus' performance. PhasicTM SL's bi component structure combines hydrophobic yarns with multi dimensional Phi yarns to elevate the level of moisture dispersion. This regulates body temperature during active phases, and dries faster during rest phases. The knit construction's mechanical stretch eliminates the need for elastic yarns that can retain moisture, but still allows the Motus to provide a performance fit that moves with the body.
