Worn as a warm midlayer or standalone outer for fast ascents in the likes of the Chamonix Valley, the Microlight Summit is a streamlined technical jacket for when weight is a concern but function is paramount.

Constructed with cutting edge Pertex® Quantum Infinity Weave™ fabric, the Microlight Summit Jacket eliminates the need for stitch through baffles, reducing weight and increasing weather resistance. Filled with 750 fill power ethically-sourced hydrophobic down, it combines warmth with increased wind and weather resistance.

Perfected for moving fast in alpine environments, the Microlight Summit features a slightly longer fit in the body, harness-compatible hand pockets, and a two-way front zip with an insulated zip baffle and chin guard to maximise comfort. Stretch nylon cuffs fit easily over gloves, while the helmet-compatible hood features an internal stretch gaiter to seal out wind. Internal stretch-bound hood seams reduce hood volume when worn without a helmet.

Inspired by decades of experience in the mountains, the Microlight Summit is a truly alpine jacket: lightweight and packable, while offering increased durability, warmth and weather resistance.
