This is a simple, non-brand backpack with two pockets on the front. I purchased it for travel, but I bought another backpack I liked better, so this one is unused. - Design: Simple design - Number of pockets: Two zippered pockets on the front, and a pocket on the back - Material: Smooth material, possibly nylon or polyester The side pockets seem like they would fit a folding umbrella, but not a water bottle. Thank you for looking.
