What’s cool about IceMule? What is IceMule even? Well I’ll tell you.It’s quite possibly the. coolest. cooler. ever. (no pun intended).With a softshell exterior, easy-to-use roll top, and padded backpack straps, this cooler is portable, leak-proof, and durable. It’s perfect for any adventure, from festival strolling to stand up paddleboarding and beach chilling. Load it up with whatever you want to keep cool, a bag of ice, and roll down the top. Let some air into the sides and your perishables are good to go for over 24 hours. The ice will keep for at least a day if not longer, but even once the ice melts, your contents will stay chilled for days.IceMule founder James Collie thought of the idea during a day hike with friends in the mountains of Virginia (where most great ideas come to fruition). When his impromptu trash-bag-lined day pack failed to keep his contents cold and his remaining possessions dry, he decided to make a portable softshell cooler. Many months and prototypes later, the IceMule was born. Check them out at icemulecooler.com.
