Black Diamond

Coefficient LT Beanie

What Our Gearhead® Experts Are Saying:

"This is the beanie I stash in every pocket during winter. It’s thin enough to layer under a helmet but warm and breathable enough for touring, running, or hitting the skintrack. You forget it's even there—until you’re thankful it is."

Built for high-output days in cold conditions, the Coefficient LT Beanie from Black Diamond is the minimalist essential we rely on for everything from dawn patrol ski laps to alpine starts. It’s crafted from Polartec® Power Grid™ fleece that traps warmth, breathes efficiently, and dries in a flash—exactly what we need when working hard in the cold.

The low-profile design fits snugly under helmets and hoods without bunching or pressure points, and at just under an ounce, it’s light enough to go unnoticed until the moment you need it. Whether we're running, climbing, or skinning, this beanie is built to go the distance.
