Product details
Thanks to their unbeatable performance and versatility, Aenergy Light styles can be used for all seasons and sports. The lightweight mid-layer combines the right amount of warmth with optimum moisture wicking and breathability and is therefore also suitable as a base layer - for ski tours in winter and on hikes in summer. With the low-cut half-length zip for temperature regulation and the laminated pocket for essentials, the Aenergy Light ML Half Zip Pull is the solution for anyone who values optimum performance with minimum weight.
