It's THE bag for the Tour du Mont-Blanc! Sleeping bags are designed with three types of insulation, each with their advantages: down, synthetic and composite (mix). Composite essentially offers the best of both worlds. Synthetic fill in the bottom section, where you lie (and therefore flatten the insulation - in any case, down would have less loft here) provides good ground moisture management. The down top gives a snug quilt-like effect. A handy compromise between weight and warmth, and a great investment. This composite three-season bag - designed for mountaineering, trekking and walking - is available in several models tailored to your specific use. With the Dreamer Composite 1300 and the irresistible feel of its peach-skin polyester lining, warm and cozy nights in the shelter await. The Dreamer Composite family comes in five temperature, weight and size options - make your mind up using our small guide thermometer.
