Rab Nexus Jacket is a lightweight and comfortable fleece jacket that serves as a reliable mid-layer on mountain trips, at the climbing crag, and on outings 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 activity and quieter stretches. The slim fit slides easily under shell garments and allows full freedom of movement, even as pace varies and the weather changes.

The fabric is a stretchy Thermic™ fleece, 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 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 flatlocked seams reduce chafing and keep bulk to a minimum, which is particularly useful when worn under a climbing harness or a rucksack.
