The best size for travel Sling bag & backpack
In this guide, we will be talking about the different bag sizes and what they can fit so you can find the best bag size for traveling. We're going to start with One Liter Sling to use as a pocket dump and go all the way to 60-liter gear haulers for rugged outdoor adventures. Basically, the best size for a travel backpack largely depends on what kind of travel you're going on and how long you'll be traveling around. Here are the best travel bags for every situation.
1 Liter Pocket Dump Sling
This size is small enough to wear through the day as you explore, but still big enough to fit everything you'd normally put inside your pockets. That is why it's called a Pocket Dump Sling. This size is handy when you're going through airport checkpoints. Instead of wasting time at the security checkpoint shuffling through all your pockets, you can pack everything in a one-liter sling bag and slide it through the scanner. This bag is also larger than you think, and can fit your phone, keys, travel wallet, passport, boarding pass and headphones. This is the perfect lightweight bag for maximum mobility as you can wear it as a sling or around your waist. Lastly, this bag can be packed into itself for easy storage when not in use.
2.5 Liter Pockets Plus
If you want to go far a bag that's a little bit bigger, but you still want to slay in sling territory, you can opt for something around 2.5 Liters. This size is often referred to as Pockets Plus. It can fit everything you carry in your pockets plus a little bit extra. So, in addition to your phone, wallet, passport and keys, a 2.5-liter sling can also fit small gaming consoles like a Nintendo Switch, snacks, a battery bank and charging cables. You may even be able to squeeze in some wet wipes and a packable rain jacket if it's small enough. Besides getting you through security checkpoints hassle-free, a 2.5-liter bag has enough room for your in-flight essentials. Just wear the sling in front so you can get access to snacks or your Switch without having to dig underneath the seat in front of you to get them. You can also use a hero clip to hang it of the seat in front of you.9-to-13 Liter Messenger Bag
A Messenger Bag has a capacity between 9 and 13 liters which allows you to bring a tablet, a small laptop, and some tech gear along when you need you need to get some work done on the road. There are also bags that are more of a cross between a Messenger Bag and a Sling Bag. It's good when you don't to lug around a full-on backpack but still have more to carry than a traditional sling can accommodate. A 13-liter Messenger Bag is a good pick for commuters that don't want to take up too much space on trains or buses. They're also convenient if you commute by bike.To get the most out of a bag around this size, consider how certain features will cater to your use case. An open main container without a ton of organization will be good for holding more items. So will the difference between 9 or 13 liters affect how much you can pack inside? It depends on the bag's level of organization and how you pack it.
