Built for the alpinist, every feature and detail of the Microlight Summit has been scrutinised to ensure it functions seamlessly. High in the mountains, it offers essential warmth at a practical pack size.

Born from the classic Microlight, the Microlight Summit is inspired by innovative new fabric development, Pertex® Quantum Infinity Weave™ ∞. This incredible technology removes the need for glue, heat and stitching when constructing baffles, increasing weather protection and boosting warmth. 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.

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 and sleeves to be pushed up for temperature regulation. While a slightly longer fit in the body, harness compatible hand pockets, insulated zip baffle and chin guard all maximise warmth when belaying. Then when conditions worsen, a helmet compatible hood with an internal stretch gaiter protects from wind and improves the fit around face both with and without a helmet.

What We Think

If you want a revolutionary down jacket then look no further than the Rab Microlight Summitt. This jacket is lightweight, packable and gives great insulation when on high peaks or mountains. Made from Pertex a brilliant Quantum Infinity Weave fabric this jacket provides you with the insulation needed for day long warmth. Pertex weaves yarns of fabric in and out of itself to create baffle tubes in one singular construction. This reduces the need for thread and reduces the overall weight of the down jacket incredibly.

This men's down jacket looks clean and smart and is highly water and wind resistant due to the Pertex fabric and the undeniable fact there are less stitching holes everywhere. This jacket prides itself on giving the wearer day long comfort and warmth and can pack down small ready for the pack or daysack. The insulation is a super high-quality 750FP Hydrophobic Goose Down which packs down to a fraction of its original size and has the best warmth to weight ration of any other insulating material. This Hydrophobic down is treated with Nikwax products to ensure they perform to the max in damp conditions.  Hydrophobic down is not waterproof it dries much faster, absorbs less water and retains loft far better than untreated down. There is a DWR coating applied to the outer of the jacket to bead water away from the fabric. 

This jacket comes with a fully helmet compatible hood that sits neat if you're not using one too! It has inner stretch seams which reduce the hood size without heavy cords and string. It has comfortable cuffs that fit over gloves and can also be pulled up the arm to give extra ventilation. If you're a climber it doesn't end there the jacket has a two way front zip so you can use your harness or ventilate more if desired. Once you're finished with this coat pack it down into it's own neat stuff sack hidden in the pocket.
