OutfitterLoft is 20% warmer than other brands at equal weight and retains its warmth even when damp. It's odorless, non allergenic, mildew and moth resistant. This handy system incorporates two individual sleeping bags that zip together for the ultimate in comfort for two, or you can separate them for independent use. Redesigned for use with available sheets to add an extra measure of warmth, comfort and washability. Roll-up straps for compact storage. Includes two 12" x 20" polyester/cotton pillows.
