Microlight Summit

10 Years On

Perfected

Built for the alpinist, the Microlight Summit was inspired by the incredible Pertex® Quantum Infinity Weave™ ∞. Every feature and detail has been scrutinised to ensure it functions seamlessly in the mountains, offering essential warmth at a practical pack size.

Inspired

Born from the classic, the Microlight Summit harks back to the original Microlight’s alpine roots. Inspired by innovative new fabric development, it combines over 10 years of learning with the latest technologies, delivering impressive results.

750FP Ethically-sourced R.D.S certified European goose down

Fluorocarbon-free hydrophobic down

Worn as a protective outer, or warm midlayer in cold conditions, the Microlight Summit is versatile and robust with a feature set honed for alpine environments. A two-way YKK zip and stretch nylon cuffs make transitions quick, allowing the jacket to fit comfortably over gloves. Alongside this a slightly longer fit in the body, harness compatible hand pockets, insulated zip baffle and chin guard all maximise warmth when belaying.

Perfected

Lightweight, packable, durable and warm - the ultimate lightweight down jacket.

InfinityWeave_Master

Infinity Weave™ ∞

Taking a new approach to baffle construction, the Microlight Summit is made from Pertex® Quantum Infinity Weave™ ∞. This innovative fabric eliminates the need for stitching, glue or heat when constructing baffles, and is instead woven to increase wind and weather resistance.

Inside, each baffle is filled with the highest quality 750FP ethically-sourced hydrophobic down. This allows the Summit to pack down to next to nothing and quickly loft again when needed, even in less favourable conditions.

When not in use the Microlight Summit’s pack size makes it easy to stow in a pack or clip to your harness.

The Microlight Family

From remote belay ledges to long days on the hill, our Microlight was first designed as a classic layering piece for alpine climbers. However, these jackets have seen far more than mountains in their lifetime. Worn under a harness, over an old jumper, with climbing pants, surf shorts and jeans - you’ll be ready to go hiking, skiing, fishing, flying and more.

Trends come and go, but the Microlight remains steadfast.
