Black Diamond Men's Alpine Start Hoody-OCTANE

When conditions shift on the ridge and wind begins to bite, the Black Diamond Men's Alpine Start Hoody in Octane gives weight-conscious climbers a fast, reliable layer of defense. Built from Schoeller stretch-woven fabric, this ultralight softshell delivers breathable, packable weather resistance that keeps you moving without the bulk of a heavier shell. The Schoeller Eco-Repel Bio treatment provides PFAS-free DWR protection, repelling light moisture while maintaining the fabric's natural breathability on high-output approaches and technical pitches.

The updated silhouette is engineered around freedom of movement. An expanded range of motion through the shoulders and arms means you can reach, pull, and clip without restriction, even with a pack on your back or a harness around your waist.

Speaking of harnesses, the drop hem is specifically designed to remain compatible with climbing harnesses, so the jacket stays in place and out of the way during technical sections. Elastic banding at the hood, cuffs, and hem works together to seal in warmth and lock out drafts, giving you reliable coverage without the need to fiddle with drawcords mid-climb.

The hood fits cleanly over a helmet, offering protection when the wind picks up without compromising your field of vision or helmet fit. Lightweight and highly compressible, the Alpine Start Hoody stuffs small enough to live in the lid of your pack or a hip pocket, ready whenever conditions demand it.

The Octane colorway adds a bold, high-visibility tone that keeps you easy to spot on snow and rock alike. Whether you are moving fast on a long alpine route or layering up at the belay, the Black Diamond Alpine Start Hoody brings performance, protection, and packability together in one versatile piece.
