Crafted with quality inside and out, the Polar Bear 12 Pack Nylon Soft Cooler is built for everyday use. The Polar Bear Nylon Series features a heavy-duty 1000-Denier Nylon outer shell, making the cooler lightweight and easily maneuverable. While this cooler looks great on the outside, it's what's on the inside that really counts. It houses 1-inch thick high density foam, giving it a high cold chill impact to keep your items cool even on the hottest days.
