Cocoon 2.0 Running Jacket – Men's

For cold-start training runs and pre-race warm-ups, the Cocoon 2.0 is our pick for runners who need just enough insulation without dragging extra weight. Its fitted cocoon cut traps body heat efficiently while the stretchy, run-specific fabric moves through your full stride without restriction. One clean black colorway that layers under a shell when conditions get serious.

• Fitted cocoon silhouette traps body heat at the start without turning into an oven mid-run
• Lightweight, run-specific stretch fabric moves with your stride — no binding, no pulling
• Packable enough to stuff and stash when you warm up on the back half of a run
• Works as a standalone layer for cool mornings or under a shell in harsher conditions
• Clean black colorway pulls double duty from pre-race warm-ups to post-run cooldowns
