Rab Mens Mythic Alpine Light Jacket


All about this product



The Mythic series features its lightest jacket designed to optimise warmth while minimising weight. This innovative piece incorporates body-mapped insulation and ultralight construction to achieve exceptional performance. The core is surrounded by down-filled baffles, while resilient synthetic insulation is strategically placed on the sides, cuffs, shoulders, and the base of the hood for efficient breathability and moisture management. The jacket utilises premium 900FP down and PrimaLoft Gold insulation, ensuring remarkable warmth relative to its weight and bulk.


In an effort to maintain minimal weight, a 100% recycled ultralight 10D outer fabric is employed. This Pertex Quantum material, equipped with built-in ripstop, not only contributes to the jacket's lightness but also offers strength, durability, weather protection, and a soft touch. With a slim fit and pre-curved sleeves that allow for unrestricted movement, the jacket facilitates easy layering and can be conveniently stowed when not in use. The outcome is a lightweight, robust, and packable insulated jacket tailored for a range of winter mountain pursuits, including mixed climbing, alpinism, ski touring, and mountaineering.

About this brand


The Rab story began in 1981 in the attic of a small, terraced house in Sheffield where Rab Carrington made the first sleeping bag to bear his name. Hand-stitched and devised with his own ingenious eye, Rab's experience from years spent in the mountains was apparent in his designs, and soon there was popular demand from Rab's friends and the growing local climbing community. Now, decades later, those honest, hard-wearing designs can be found all over the world; wherever adventurous individuals face up to the elements. From Himalayan peaks to cold, crisp evenings around a camp fire. This began as the brand's story, but it also belongs to those who've loved and cared for each and every one of our products. Who've made them their companions on long trips and expeditions.
