Review on 🎒 DAUSROOB Insulated Cooler Backpack 27L - Lightweight, Leakproof, Large Capacity Cooler Bag for Men and Women - Stylish Fashion Design - Ideal for Work, Picnic, Camping, Hiking, Fishing, Beach - Holds 33 Cans by Doug Twilights

I didn't know there was a waterproof zipper until I got a backpack which my husband loved. Sometimes we use it to carry groceries to make it easier to carry around the apartment. I can transport frozen seafood and meat in it and then put it in the trunk of my car without worrying about the ice water leaking out. Everything is high quality and easy to clean. The top layer of the bag is also covered with waterproof material. And it comes with a bottle opener.
