The Coca-Cola PTX backpack cooler by Picnic Time features a fully-insulated, water-resistant interior liner so it may be used as a food and beverage tote, grocery or lunch bag, or an all-around activity pack. Made of durable polyester with padded, adjustable backpack straps, this cooler pack is comfy and versatile. It has five separate pockets, a front-mounted stretch cargo cord for attaching a towel or sweater, and an attachment harness that will secure it to a golf cart. This cooler pack speaks for itself, and it is no wonder we labeled it the PTX for 'Picnic Time Extreme'. It performs a wide variety of functions, can store items beyond its visual confines, and makes a super-cool all-around backpack cooler for people on the go. Measures 12..
