Built to roam just like you are. Don't be fooled by it only weighing 4 1/2 pounds. It keeps ice better then our Outfitter 22. The trap mouth design keeps the opening closed, and keeps the good stuff cold, even when you forget to zip it back up. Includes a handy side pouch for your cell phone, utensils and napkins. Fits almost anywhere, high quality fully welded non toxic premium liner keeps food safe and stops the soak. At 20 liters or 21 quarts, it makes a great little grocery getter, day, and a little fishing. It even includes a shoulder strap, molle tie down points, a water-poof zipper, and a silicon lubricant. The cooler will also float if you fall off that SUP. and works great with our hard sided ice packs.
