Cool-Ven features tough woven (600d pu) fabric outer panels with a (three 28oz. meal) cool insulated lower chamber, mesh pockets and a spill resistant liner.  Attached to the top of the bag is a removable (zippered) insulated compartment which houses a 110-volt (55 watt) electric heating element (w/ a 48 inch. cord) designed to reach temperatures of 210 degrees Fahrenheit.  The element is designed to be compatible with flat metal and all microwave safe containers.  A side mesh pocket with elastic lip has ample space for a full sized, 24 oz. shaker or water bottle.  The rear of the bag has a convenient luggage strap for sliding onto your collapsible suitcase handle which adds convenience during travel.  Directly behind this strap is a slim Velcro pocket for storing your travel documents, ID’s, etc.  A secure zipper pocket on the side of the bag has both mesh and fabric, elastic pockets along with a slide lock key hook for keys and other accessories.  The bag is finished off with two handles and one adjustable shoulder strap.  Should you decide to detach your heating chamber, there is a second handle on top of the cooling chamber which makes it convenient to use your two Cool-Ven compartments separately.
