With its WindStopper stretch fabric, the Black Diamond Men’s Flow State Jacket is perfect for high aerobic activities in cool and windy conditions. This versatile jacket works well on its own during fall trail runs, high-elevation approaches, or on the skin track. But, with an athletic fit and low-profile design, it also works well as a mid-layer while you’re skiing or mountaineering. Windproof and stretchy, this softshell protects from the elements, but doesn’t inhibit movement. Two zippered hand pockets and a zippered chest pockets keep a few things handy while you’re in the mountains, and the low-profile cuffs are designed to not interfere with your shell when you’re utilizing the jacket as a mid layer.
