Rab Nexus Jacket is a lightweight and comfortable fleece jacket that serves as a reliable mid-layer on mountain trips, at the crag, and on routes across varied terrain. The jacket regulates temperature effectively, dries quickly, and feels soft against the skin, making it a strong choice during both high-output effort and quieter sections. The slim fit slides easily under shell garments and allows full freedom of movement, even as pace varies and conditions change.

The fabric is a stretchy Thermic™ fleece at 178 g/m², a blend of polyester and elastane that strikes a good balance between warmth, flexibility, and breathability. The jacket packs down easily and is ideal within a layering system. A soft, close-fitting collar and double cuffs increase comfort and help to retain warmth.

The jacket features a full-length YKK VISLON zip with chin guard, and two spacious hand pockets with YKK zips and mesh lining for practical storage. Flat seam flatlocking reduces chafing and keeps bulk to a minimum, which is particularly useful under a climbing harness or rucksack.
