This zip-through sherpa fleece is a high achiever in the world of layering. Its cosy outer and pure cotton-jersey lining are super-comfortable and warm – wear it under a jacket when there's more than a nip in the air. We've given it a neat fit with the stretchy hem and cuffed sleeves (spoiler: look out for bursts of contrast colour). Ribbed detailing at the sides creates a sporty feel, while concealed pockets keep essentials close.
