See The 10 Best Carry On Backpacks on Ezvid Wiki ►►
Fact #1. They aren't just for kids. You're probably used to seeing everyone at the airport with spinner bags, but that may be more than you require. If you have to check a bag because you're bringing liquids or if you're just going away for a couple days, consider a backpack. Modern styles look great while letting you comfortably carry your belongings through the terminal on your shoulders.
Fact #2. Don't go too big. Kids on backpacking trips in Europe sometimes use larger packs of 85 liters or more. Not only do you probably not need that much for a weekend getaway, you'd also have to check the bag and be forced to wait at the baggage claim. Consider your airline's carry-on size requirements and get a bag that can easily fit in the overhead compartment where you can access it.
Fact #3. Item retrieval is key. While on your trip, you don't always need your keys, passport, iPad, or other items on your person, but you want them easily accessible. A backpack with pockets and compartments designed for these items makes them easy to get to so you won't be rummaging around looking for them.
Fact #4. They can be laptop-ready. To stave off boredom during the flight or get some extra work done during your trip, you'll want your laptop with you. Check the measurements before you buy so that you'll know it's built for the size of computer you want to put in it. Padded pockets ensure that your computer won't get damaged during the flight.
Fact #5. You can protect yourself form soreness. If you fill your pack up, your shoulders may get sore carrying it around. Finding a model with a handle and wheels or sporting a waist strap can eliminate the discomfort and make your trip a breeze.
