KSB 0˚ Synthetic Realtree® Xtra Sleeping Bag

    Realtree camo and lofty Klymalite™ synthetic insulation combine in a performance sleeping bag geared for four-season backcountry travel. Warm and durable, the synthetic fill insulates even when wet, and the high tenacity fabrics are tough, light and comfortable. A draft collar, over-stuffed foot box, insulated mummy hood and flexible baffles at the body’s core all work together to minimize heat loss for greater thermal efficiency. The expanded chest area and flexible baffles provide room to move, and a stash pocket keeps small items right at hand. Pair it with one of our Inertia or Static pads for a warm, reliable, comfortable backcountry sleep system.
