A Black Diamond jacket with breathable insulation PrimaLoft Silver Active technology that keeps you comfortable whether you're cruising up the skintrack, traversing a wind-blasted ridge, or hoofing it up a bootpack. The helmet-compatible hood is quick to flip up when the winds pick up, and lightweight stretch fabric allows full range of motion for tricky maneuvers on the ascent. The jacket stows into its internal chest pocket with a carabiner clip loop so you can clip it to your harness or stuff it in your pack when the weather changes abruptly.
