With a huge selection of down and synthetic sleeping bags you’ll be spoilt for choice in our sleeping bag department. We have selected a full range from micro / one season sleeping bags to four season expedition sleeping bags all from top brands like Mountain Equipment, Fjallraven and Deuter. Down sleeping bags give you the best warmth to weight ratio while synthetic sleeping bags work better in damp conditions. If size/bulk is critical then down bags will usually pack down to about half the size of synthetics. One tip we always give to shop customers when buying a sleeping bag is to choose a bag that can cope with temperatures lower than the lowest temperature you are expecting. If it's extreme cold you're heading for then fear not, some of the bags below are designed to handle temperatures down to -30.
