The Black Diamond Coefficient Hoody is a technical fleece midlayer built for active use in the mountains, where effective temperature and moisture management are essential. Its Polartec® Power Grid™ fabric features a distinctive grid interior that reduces bulk, retains warmth and helps move moisture away from the body.

The full-length front zipper makes it easy to regulate temperature while climbing or moving uphill. The low-profile hood fits comfortably under a helmet, while lightweight stretch cuffs with integrated thumb loops provide a secure fit and extra wrist coverage.

A zippered chest pocket keeps small essentials close at hand. The slim fit allows the hoody to be worn comfortably beneath a shell jacket without restricting movement.
