A staple for any climber, mountaineer or walker our Nucleus jacket is your go-to lightweight technical fleece.

One of Rab's most popular products, the Nucleus is at home in the hills. Whether you choose to wear it as a mid-layer or a baselayer, this jacket is no stranger to hard work and quickly moves any moisture and sweat away from your skin, keeping your core warm and dry. 

Made from Rab's own Thermic fleece, a soft, stretchy low bulk fabric, the Nucleus Jacket has a close fitting under-helmet hood designed to keep out any drafts and flatlock low bulk seams to allow the outer to move easily under a shell should you need to layer up.
