We’ve taken everything we know about lower impact design and applied it to what we do best. These resilient synthetic bags are filled with 100% recycled Stratus™ insulation, and lined and covered with a tough, 20D, recycled Atmos™ fabric with ripstop. Hardwearing, warm, and dependable, they are fast drying and cope with condensation or damp conditions, ideal for the exposed bivi ledge or taking refuge in a snow hole.
The Solar Eco 4 is insulated with a double layer of Stratus™ insulation arranged in a concertina structure to trap warm air. 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. Perfect for four season climbing trips, mountain bivis, 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 night-time temperatures plummet.
