PTX Backpack Cooler

Perfect size. Convenient pockets

Great for hiking and biking

I love this backpack cooler. I had one for years and used it so much that it finally started wearing out so I tracked down another one. It's a great size for hiking and biking. I put my bladder bag in there, some lunch and then assorted other needed supplies. It's also great for solitary beach picnics. I like its size, all the little pockets and compartments, and the fact that it's designed to keep a steady temperature.
