Stay Toasty

Lightweight shell jackets have their place, but on cold days you’ll be glad to have the Black Diamond Boundary Line Insulated Jacket in your gear closet. It starts with Black Diamond’s waterproof and breathable BD.dry™ material, which is not only stormproof, it’s also stretchy, for outstanding freedom of motion. It gets just the right amount of warmth from 60g Thermolite® synthetic insulation, which stays warm even if it gets wet. And the details, like a helmet compatible hood, zippered sleeve pass pocket, and full length pit zips make this jacket ideal for spinning resort laps in everything from whiteout storm conditions to crisp bluebird days.
