This Black Diamond shell jacket is seriously technical outdoor gear that works for everything from gym climbing to big mountain adventures. The standout feature is the GTT Empel breathable water protection technology - it's this revolutionary water-free and PFC-free DWR treatment that outperforms and outlasts traditional waterproofing. The fabric is air permeable, which means it actually breathes well during high-output activities so you don't get all sweaty inside. There's a YKK-zippered chest pocket that stows away neatly and has a carabiner clip loop for attaching gear. The hood is climbing helmet compatible, which is so important when you're actually using it for its intended purpose. The hem is adjustable to seal out wind and weather, and the cuffs are elastic for a secure fit. It's designed with input from actual climbers, so the features are practical and well-thought-out. The fit is athletic without being restrictive, giving you freedom of movement for reaching and climbing. Whether you're dealing with rain, wind, or spray, this jacket has the protection you need while still being breathable enough that you can wear it during active moments. Black Diamond knows climbing gear, and this shell delivers the performance you'd expect from them.
