Great for Hunting, Camping, Tailgating, Backpacking, Paddle Boarding, Sailing…any outdoor activity. The IceMule Pro Coolers is the world’s most portable high-capacity, high-performance soft cooler. It combines the portability of a backpack with the performance of a hard cooler. It keeps ice intact for up to 24 hours. And, it rolls up for storage in its own stuff sack. Unlike other soft coolers, the IceMule Pro is not sewn together and it has no zippers – sewn seams and zippers leak. Instead, the IceMule’s patented design utilizes welded seams and a double-layered shell that houses insulating foam between the layers – in essence creating an incredibly well-insulated dry-bag cooler that can carry ice without leaking. Plus, the Ice Mule’s watertight roll-top closure and side release buckle make it easily accessible and the padded back-strap system makes it highly portable.
