Sleep warm on cool evenings with our Scout bag. The rectangular construction permits ultimate freedom of motion, and a full 3. 0 lbs of poly-therm hollow synthetic insulation will not lose insulating efficiency If it gets wet. A polyester shell provides a durable, attractive exterior, and interior polyester taffeta lining that's smooth and comfy. With the included stuff bag (with built in compression straps), you'll be able to break camp and stow this bag in a hurry.
