Made from bluesign® approved 100% recycled polyester, it's light, breathable, and packed with performance—thanks to moisture-wicking fabric, movement-mirroring stretch, and thermo-regulating ActiveTemp™ that adapts as your pace shifts. The two-layer cowl neck brings in extra warmth up top, while ergonomic thumb holes lock sleeves in place. A kangaroo pocket warms your hands, with an internal mesh sleeve to stash your phone without the bounce.
