This is super roomy, zips completely open (like a suitcase — so it’s easy to find what you need), has plenty of pockets (including one for shoes and a separate wet bag!), and a strap that slides down over your luggage handle for easy transport.
Promising reviews: “I bought this backpack for work. It’s the BEST backpack I’ve ever used. I needed one with several pockets and not too big or heavy. I found that with this backpack, I can fill it and still have room! There’s even a shoe and clothing compartment for traveling! The straps are just wide enough to stay on your shoulders especially with the snap straps in front. I also love the color, and it’s true to the picture color. If you’re looking for lightweight with tons of pockets, this is what you need!” —Kelly Miller
“This is a perfect size backpack for traveling on a plane as your personal item, especially to international destinations. You could fit rolled-up clothes in here for another week, and it has a very handy shoe bag and tons of places for your electronics. This will be an excellent addition to my carry-on suitcase. Best purchase all year. I consider myself an expert on travel bags. I have way too many. It’s smaller than it looks but so roomy.” —AP
