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. The Polar Bear houses 1-inch thick high density foam, giving it a high cold chill impact to keep your items cool even on the hottest days.
