The Climate Shirt is a close-fitting running layer in 100% recycled polyester. Its multidimensional woven surface moves moisture quickly, while four-way stretch and shaped seams follow the upper body through long efforts.
A quarter zip regulates coverage, supported by spiral elbow darts and a contoured back seam. Thumbholes extend protection over the hands without adding another layer.
A discreet zipped side pocket holds a card or key, and reflective details sharpen visibility after dark. Warmth and airflow shift with the run rather than locking the body into one temperature.
