From the Khyam range, the Ultralight 800 is a 2 season sleeping bag that is ideal for the summer backpacking trip or adventure abroad especially where weight is a premium. Packing small the bag is ideal for space saving trips. The Ultralight weighs in at around 1kg. The bag can be combined with other bags in the range, such as the Ultralight 600, to offer exceptional warmth in colder conditions yet with the two weighing still less & taking up less space than a conventional bag. The filling used in the Ultralight range has insulation properties that are the equivalent to down, dries more quickly, is water resistant, highly breathable & hypo allergenic.
