The Outwell Pelican M is a self-inflating cool bag that fills itself with air by loosening the valves. This significantly improves insulation. The cooling compartment is lined with aluminium foil, which provides excellent insulation. This combination of air and aluminium keeps the contents of the cool box cool for up to 15 hours (tested in combination with an Outwell L cooling element). The Pelican M cool bag is equipped with a large zippered flap, two sturdy handles and an adjustable shoulder strap. After use, the cool bag can be quickly deflated.
