Calling the Black Diamond Men's CoEfficient Fleece Jacket a versatile mid layer might be an understatement considering the fact that you take it out on every cold weather excursion. Its high range versatility is due to the unique Polartec Power Dry High Efficiency fleece fabric that covers your body with soft warmth. Not only does it warm you, it's remarkably breathable and dries fast so you stay comfortable while you hike up powder capped peaks or pick up a sweat during climbing expeditions whether they're long alpine ascents in the Tetons or short sport routes late in fall. And it's especially durable to withstand all the beatings you inflict on it all year long. A slim fit pulls the CoEfficient close to your body to both help you layer up for ski sessions and reduce bulk to your climbing attire. Stretchy cuffs feel soft on your wrists, and Black Diamond lined the neck with cozy chamois for additional comfort. One chest pocket is all you need for your phone and wallet while you climb up some peaks or drop down them.
