ROCK FRONT 600 is built for winter trips, cold off-season use, and mountaineering. Сenter-zip convertible mummy bag concept gives it more versatility than a standard mummy sleeping bag, making it easy to use as a warm sleeping bag, a blanket, a quilt, or a hammock underquilt.
Full-length center zip lets you open bag completely and use it as a blanket when conditions are warmer. Bottom slider also makes it easy to vent heat from leg area. For couples traveling together, two compatible sleeping bags can be zipped together into one shared setup.
Insulated with 800 fill power goose down, it stays warm, lightweight, and compact. DWR-treated down and shell fabric also help it handle damp off-season conditions better.
