Khyam Vss Ultralight 1000 Sleeping Bag.
From Khyam's popular VSS range, the Ultralight 1000 is a 2 to 3 season sleeping bag ideal for autumn winter backpacking especially where low weight is crucial.
Double layer construction keeps the insulation evenly distributed, unlike down filled bags which are notorious for it clumping and producing cold spots.
Thermlin filling used in the whole range dries more quickly than down but is just as warm. The Ultralight 1000 is wind resistant and highly breathable while remaining extremely compressable. Combined with Ultralight 600 or 800 for a go anywhere system for the cold nights, yet the two together still weigh less and take up less space than conventional sleeping bags and will be warmer weight for weight.
