Ytonet Travel Backpack for Men & Women, Water-Resistant Sports Backpack with Shoe Compartment, Fits 15.6-inch Laptop – Ideal for Workouts, Camping, Hiking, Gray

This is technically 2 inches too tall to count as a “personal” bag on the plane, but it works well as a carry-on if you pack light. I love the shoe pocket at the bottom. This is handy for travel and also for carrying a second pair of shoes to the gym (flip flops for the sauna and shower). There are lots of excellent pockets. I use the clear one for electrolyte powders and snacks and the front pocket for chapstick, keys, earbuds, and chargers. The backpack easily holds a couple of changes of clothes, a pair of shoes, snacks, a sweat towel and Turkish towel, toiletry set, makeup bag, and water bottle, making it perfect for a weekend getaway, the gym, or the pool. I also sometimes take it with my laptop to work if I plan to go to the gym afterward as it has a laptop pocket with Velcro strap to hold it in place. On vacation, I use that pocket for my embroidery set and a book. I've had it for a few months, and it is holding up well so far.

Great backpack for my granddaughter she especially liked the convenience of many pockets for storage and an USB cord for connecting a power bank.
