If you're active in winter, doing mountain walking, winter sports, alpine climbing or simply travelling and trekking in cold or high places, Rab have made the super warm Boulder Hoodie for you. Exceptional warmth to weight means that the genuine Polartec Thermal Pro fleece really keeps the warmth in and the cold out without being heavy, bulky or cumbersome. You can use it as an attractive outer garment in it's own right or it fits snugly enough to use under outer shell clothing if the weather really closes in. But if you can't imagine why anyone wants to go out in the cold, then snuggle into this indoors or out, and smile while others are shivering.
