Literally used a couple of times and in great condition (used for an event). Complete with stuff sack. This is a great bag and quality brand alongside the likes of RAB / Mountain Equipment / North Face etc. This is true mountaineering bag, but also equally good for those going camping in the UK but want to be nice and warm! By prior arrangement from Watton At Stone (SG14) or in London (Green Park or Finsbury Park). The Universe SL sleeping bag is part of Mountain Hardwears Quantum collection. The Quantum series means there is seasonal and temperature versatility in this mountaineering bag not found in its competitors. The Universe SL is a 600-fill down bag with a 0 degree F -18. However, by including an expandable and insulated 8-inch draft tube this bag can be just as comfortable during a glacier whiteout as it can be on a summer mountain side. The hot air comes out of the bag by unzipping the tube in warmer temperatures and with the pull of a zipper can eliminate dead air space in colder conditions. Claustrophobia doesnt stand a chance in this adaptable mummy. In addition to the possible 8 inches of elbow or layering room provided by the draft tube, the Universe SL sleeping bag also has a multi-baffled footbox. The comfort footbox has improved fit by allowing for natural foot position while the multi-baffle increases warmth. Meanwhile, the eight-baffle tailored hood keeps the most important extremity (the one that dreams of future summits) warm and comfortable throughout the night. This waterproof and breathable sleeping bag is as functional as it is durable. The tucked-stitched baffles work to prevent threads from snagging and breaking while being packed, unpacked or pulled out and under the stars. And one need not worry about fabric catching during late night temperature regulating episodes or cold hand camp set up, as the zipper snag guards keep your bag safe and snag free.

Stuffed diameter: 7 in/17.8 cm. Stuffed length: 1 ft 4 in/40.6 cm. Note – the stuffed dimensions are for the stuff sack and not in a compression bag.

Quantum Bags all have the Quantum Expander, an ingenious way of adjusting the volume of your sleeping bag to respond to changing conditions. This bag category allows you to choose a sleeping bag with either down or Polarguard 3D fill that will serve you over a much wider temperature range than previously possible.

Performance-cut mummy shape is more efficient and saves weight, reducing girth at shoulder, hip & legs. Multi panel, contoured footbox. Contoured hood forms around head to seal in heat. Differential cut maintains maximum loft. Expandable draft tube provides additional room for warm temps and layering space for colder temps.
