i fit my 32oz in the water bottle holder, and i’ve put everything i need (so far) in the bag and still have plenty of room, highly recommendMy son loves it! It even has an extra pocket that his old backpack didn't have. It's perfect for him he carries the school laptop, school books and a football. Must buy!!Love this bag! I just graduated nursing school and needed something that was accommodating in size, with many compartments.This bag is perfect for carrying to work at the hospital. It’s big enough, but not overwhelming. Fits everything perfectly. The quality is great so far. I appreciate the depth of the compartments. The zippers do not feel cheap. I can carry all of my personal items & nursing equipment without having shoulder or neck pain. The straps are made with small pads to minimize the weight of the bag. The bag does not fall forward when filled and sitting on the floor/chair.I kept it simple and purchased it in black. The shipping was fast. The packing was excellent.It’s worth every penny’sIt great for what i use it for will buy agin down the roadDaughter picked out & loves this. Super big & good qualityalways a great back packMy daughter loves this backpack and decided to use it again this year after using it all year last year. I threw it in the washer and it held up fine. She has the Electric Palm color and that suits her. It's roomy and durable and she loved being able to choose a unique fun pattern.Mochila de buen tamaño ideal para guardar los libros, libretas, plumas, lápices, ropa para un viaje express
