Dynafit M Blacklight Hybrid Thermal Jacket

The Men's Blacklight Hybrid Thermal Jacket is built around Octa®, a hollow-fiber knit that holds warm air inside the fiber rather than in a layer of pile on the surface. That delivers thermal performance at very low weight and keeps the jacket breathing on a climb instead of turning into a heat trap at the first steep pitch. Hybrid construction backs that active insulation with more protective fabric across the wind-facing panels, so a cold skin track does not automatically call for a shell. Positioned as a touring mid layer rather than a belay piece. Men's fit, cut close.
