During a warm spring hike, James Collie decided to rig a portable cooler out of a daypack and several plastic bags. After the hike, James set out to design an easy-to-carry cooler bag he could wear like an outdoors backpack. A decade of research and development later, and James' IceMule coolers are the leading high-quality adventure coolers for pursuits that range from backcountry hikes to tailgating football games. The company’s line of durable, fully waterproof bags keeps your beverages icy for up to 24-hours and roll closed, preventing leaks or rain infiltration. The bags also feature comfortable straps for over-the-shoulder carrying and pack-away small when empty. Models like the Pro Catch and IceMule Classic coolers come in a range of sizes, perfect for camping, fishing, or family gatherings in remote settings.
