Sleep warm on cool evenings with our scout bag. The rectangular construction permits ultimate freedom of motion and a full 3 lb of polytherm 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.
