With the thickest insulation of the entire Outfitter family of premium coolers, the 35 is the toughest and most extreme cooler in its size. The Outfitter 35QT Cooler is made of durable kayak plastic, and filled with explosive high-density insulation. It's lockable and packable, at only 22 pounds empty weight. Our signature straight wall construction means it fits where you put it, without wasted space for the common muffin top lids you see on other premium coolers. It's easy to use with our EZ-Cam latch system, and easy to secure to your rig with 2" tie down slots. And for those of us with OCD, The 35 fits not just one, but two cooler baskets (sold separately).
