A stretchy technical top with strategically zoned panels for active comfort and temperature regulation, the Women's Comet Long Sleeve Crewe Impulse is a highly functional layer for moving fast in chilly conditions. The Comet Long Sleeve Crewe features our 150gm corespun fabric, merino wool fibers wrapped around a nylon core, for added strength and durability which retains next-to-skin softness. In the underarm panels, we use 120gm eyelet merino mesh fabric to aid in ventilation during high-output days. Bonded seams eliminate chafing, while thumbhole cuffs add a touch of warmth and functionality, and make for easy layering. Our 'Impulse' print is organically inspired by the calmness and serenity of nature, interrupted by bright bursts of energy, which mirror your savoured moments on the trails.
