Coofay Lightweight Waterproof Anti-Theft Travel Backpack for Women & Men - Gym, College, Sports & Carry-On Backpack for Hiking, Commuting & Daily Use

I wasn't sure what level of quality I would get from this due to the price but bought it based on the reviews. I was pleasantly surprised. The zippers seem very sturdy and it holds quite a lot. We bought for a cruise trip and they worked perfectly. They are sized so they fit within airline size restrictions as a personal item so you can fit them under seat and take a carry on. They were handy for shore excursions for use as a day pack especially the compartment for wet items/shoes. The straps are padded well enough to be comfortable when stuffed full. I also like the strap that allows you to hang it off the handle of your rolling carry-on. Family members on our trip liked them so much we gifted some for Christmas. Very happy, good product.
