Rab Khroma Diffuse GTX Womens Shell Jacket Dark Melba
Dependable mountain protection, thoughtful ski features and adaptable comfort for demanding days on snow.
The Rab Khroma Diffuse GTX Womens Shell Jacket is built for skiers who want reliable weather protection through a full season of mountain use. From exposed chairlift rides to fresh powder descents and the climb towards your next line, its durable construction and practical adjustments help you stay comfortable as conditions change. A longer cut provides coverage around the hips, while articulated sleeves allow natural movement when planting poles, reaching or carrying skis.
At its core is a robust 70D, three-layer GORE-TEX fabric with an ePE membrane and a 28,000mm waterproof rating. This waterproof, windproof and breathable construction shields you from rain, snow and cold gusts while allowing moisture vapour to escape. The uninsulated design gives you control over warmth through your choice of layers, with two-way underarm vents providing additional cooling during bootpacks, uphill travel and milder weather.
The details are designed around skiing in real mountain conditions. A helmet-compatible hood adjusts with one hand, the stiffened peak adds shelter around your face, and a removable powder skirt helps keep snow outside the jacket. Extended cuffs fit securely around gloves, mitt-friendly hem adjustments help seal out draughts, and a two-way front zip adds flexibility around the lower body. External pockets and a deep internal dump pocket keep essentials, gloves or climbing skins close to hand.

FEATURES & TECHNOLOGY

- ePE Waterproof Membrane: Provides a barrier against rain, snow and wind, with a 28,000mm hydrostatic head. Moisture vapour can escape through the fabric, helping manage comfort as your activity increases.
- Robust 70D Face Fabric: A durable outer suited to repeated ski days and use with a backpack. The water-repellent finish encourages moisture to bead on the surface.
- Adaptable Shell Design: Choose a warmer midlayer for cold resort days or lighter layers for spring skiing and uphill travel. The shell provides weather protection while your layers determine warmth.
- Controlled Ventilation: Two-way underarm zips let you release heat while keeping the front of the jacket closed, giving you useful temperature control on strenuous climbs.
- Snow-Sealing Coverage: The longer cut, adjustable hood, extended cuffs and removable powder skirt work together to reduce gaps where snow and draughts can enter.
- RECCO Reflector: An integrated passive reflector helps rescue teams equipped with RECCO detectors locate the wearer during a search.
