The Northstar Coretech 3.5 multiple layer synthetic sleeping bag carries light and keeps you warm. Oversize designed mummy bag accommodates most sizes of people. With a survival temperature down to 0°F (-17°C) this bag is great for 3 season tent camping. Carry it backpacking with it’s ultralight 5.5lb trail weight. Hollow fiber silicone fill material has excellent compression to loft expansion characteristics creating an excellent thermal barrier for the weight. Richly colored rip-stop shell fabric is soft to the touch and rugged enough to last a lifetime. Advanced thermal insulation elements like a full-length zipper draft tube, chest baffle, and hood baffle, keep the heat around your body. A jumbo two-way, self-repairing #10 zipper is easy to grab with its extended reflective fabric pull tabs. Coretech’s mantra of Buy It For Life extends into every thread in our sleeping bag – each stress point is box stitched and edges are always double-stitched – it is built to last. Product zipped-up dimensions are 86” long by 36” wide by 24” tall with gusset sidewalls. All Coretech bags include a durable compression stuff pack with a drawstring closure and a buckle clipped flip-over cap.
