The Coleman? Oak Point? 30 F Big and Tall Sleeping Bag is designed to keep campers up to 6 feet 4 inches tall comfortable in temperatures as low as 30 F. You'll appreciate that it is built to last season after season thanks to Fiber lock? construction that keeps insulation from shifting. After a peaceful night of rest, enjoy easier packing with roll-control fasteners that hold the bag straight as you roll and no-tie cords that keep things cinched tight for compact storage.
