Stay warm during your most demanding vertical pursuits with the Rab Women's Nucleus Fleece Hooded Jacket. Its stretchy, mid-weight fleece traps your body heat and wicks sweat away from your baselayers for lasting warmth and dryness, and fits seamlessly under a shell or over a baselayer, making it a mid-layer you'll reach for over and over again. The under-helmet hood adds to the technical nature of the piece, keeping your ears and head warm underneath your climbing helmet, while the full-length zipper makes for easy layering and allows you to let some cool air in if things heat up on your hike to the base of your chosen route.
