Review on Ultimate Double Deck Insulated Cooler Backpack: Leakproof, Spacious, Lightweight, and Perfect for Men, Women, Work, Travel, Hiking, and Beach Adventures by James Mayberry

The thing is amazing. I use it for disc golf. If you are a disc golfer, this article is for you. The top part fits in a disced palm (it zips up and contains about 9 discs inside), and your cold drinks fit in the bottom part. It doesn't leak, so feel free to use it as dry storage if you need to sail or take it through the water. The side pockets are deep enough to keep your water bottle from tipping over when you lean forward. The bottom cooler fits my 1 gallon water jug with ice packs, snacks and a few beers.
