Campers up to 5 feet 11 inches stay warm and cozy on cold nights under the stars in temperatures as low as 20°F with the Brazos™ 20°F Sleeping Bag. You'll appreciate that it is built to last season after season thanks to Fiberlock™ 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 in the included stuff sack.
