These resilient synthetic bags are filled with 100% recycled Stratus™ insulation, and lined and covered with a tough, 20D, recycled Atmos™ fabric with ripstop. Hard-wearing, warm, and dependable, they are fast drying and cope with condensation and damp conditions.  The Solar Eco 1 is built with a complex construction to maximise warmth without bulk. It is insulated with a double layer of Stratus™ insulation on the upper, arranged in a concertina structure to trap warm air. For reduced weight and bulk, the base of the bag has just a single layer of insulation. 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. Packing down to just 30cm x 18cm, it’s incredibly low bulk and stashable. Perfect for summer climbing trips, bivis in warm climates, and backpacking adventures.  The Solar Eco has an adjustable hood which can be cinched in snug around the face to shut out the chill and an adjustable neck baffle to stop the heat escaping. The ¾ length zip has an additional baffle along its length that acts as an effective draught excluder with an anti-snag zip guard. The wide mummy fit offers space to find your most comfortable sleeping position, with room for extra layers should nighttime temperatures plummet.
