Black Diamond Men's Alpine Start Jacket

An ultralight softshell built for athletes who need weather protection without the weight penalty. When conditions shift mid-route and you need something between a base layer and a hardshell, this is the jacket you reach for.

Highlights

• Schoeller stretch-woven fabric — A highly breathable, weather-resistant softshell that moves with you on technical terrain without restricting reach or arm movement. Packable enough to stuff in a pocket and light enough to forget it's in there until you need it.
• Eco-Repel Bio DWR without PFAS chemistry — Effective water repellency without the environmental concerns of traditional fluorinated treatments. A meaningful distinction for climbers who spend time in sensitive alpine environments.
• Increased range of motion — Updated silhouette cut for unrestricted movement on technical climbing moves where shoulder and arm mobility matter most. Stays out of your way when you need to reach.
• Climbing-helmet-compatible adjustable hood — Fits cleanly over a helmet without bunching or shifting. Elasticized for a secure fit when the wind picks up on an exposed pitch.
• Drop hem with harness compatibility — Longer in the back for added coverage and cut to work under a harness without riding up or bunching around your waist loops.
• Stows in chest pocket with carabiner clip loop — Packs into its own pocket for easy storage on the wall or in your pack. The carabiner loop keeps it accessible on a gear loop when you don't need it.
• Elasticized cuffs and hem — Seals out wind and cold without requiring adjustment mid-climb. Stays put through dynamic movement.

Best for

Weight-conscious climbers and alpinists who need a packable, breathable softshell layer for ridgeline wind, light weather, and variable alpine conditions. A natural companion piece for technical routes where conditions change fast and every gram in your pack is evaluated.
