Even in the 80s it was all about layering. But only a fleece born on Dean Street had the complete consent of the mountaineering community. The Prism is for purists. It goes wherever you go. Without it you’re lost.

A note about sizing: The Dean Street collection is unisex, with ‘oversized’ fit. If you asked our advice, we’d recommend men choose their regular Berghaus size; women may want to order a size smaller, but how you wear it is your call.
