The Miller Insulated Backpack from Herschel Supply Co. has a checkered pattern throughout, and keeps your drinks cool all day while on the go. A 22 liter capacity in the insulated main compartment equates to 20 cans being cooled at once, while the leak-proof liner keeps the bag dry even with ice. Made of 100% recycled materials, the durable backpack has 2 smaller zipper compartments on the front, dual mesh side pockets, a reinforced base, and is complete with a key ring bottle opener, heavy-duty adjustable shoulder straps, special rubberized brand patches, and dual top haul handles for added strength.
