Jam-packed with tech and built with recycled materials, the Solar Ultra embodies our drive to create more sustainable gear at the pinnacle of performance. Fast drying, lightweight and robust with heat reflecting TILT technology, the Solar Ultra 1 offers excellent warmth for its weight. Its narrow, tapered mummy shape reduces bulk and weight further, ideal for fast and light adventures in cool temperatures.

Featuring a triple layer of 100% recycled Stratus™ Eco insulation arranged in a concertina shape, the Solar Ultra mimics the performance of down in a lightweight, featherless package. Reducing radiant heat loss by up to 15%, our built-in TILT technology substantially improves thermal insulation without compromising pack size, breathability, or weight. The elastic internal quilting brings the lining and insulation closer to the user, helping to reduce pockets of cold air. The localised quilting simply means that the stitching which holds the insulation in place has been minimised to reduce the chance of cold spots.

It has a ¾ length main zip with a baffle along its length to prevent heat from escaping and an adjustable neck baffle to cinch in snug and keep the heat in. Completed with a tough, 20D, recycled polyester Atmos™ outer, the Solar Ultra is the definitive synthetic sleeping bag for alpine use or lightweight bike and backpacking missions.
