Because of this, when we talk about a “30-liter backpack,” it’s reasonable to assume that the main compartment or multiple compartments make up 30 liters in total.

A majority of 30-liter backpacks have the exact internal dimensions as their overall dimensions. However, the interior measurements of the main compartment differ from the overall sizes of a backpack.

Although main compartment size may be comparable, the overall size of a 30-liter backpack can vary considerably owing to external pockets, additional compartments, and other factors.

Who Should Buy A 30L Backpack?

30L backpacks are perfect for short-term traveling and incredibly excellent for day trips. If you like to pack light and enjoy having a small bag, then this one will be good for you to use every day without struggling with it.

However, we all know packing light can cause problems when it comes to finding specific things in your backpack. It is where the larger sizes come in, especially if you travel long-term or are shopping for a bag for your kids to use at school.

And if you’re searching for a business travel backpack with a laptop sleeve, the 30-liter bag would be an excellent option. It will fit a laptop and some paperwork but not much else.

Furthermore, the 30 Litre bag may be used as a travel backpack, hiking backpack, regular backpack, or laptop backpack.

What Should You Look For When Shopping For A 30 Liter Backpack?

Now, you’re talking about the 30-liter backpack, and if you’ve decided to buy one, there are a few things to consider before making your purchase.

Waterproofness – Since you will be spending a lot of time outdoors with your backpack, the number one thing you should look for in a 30-liter backpack is its water-resistant quality.

Just because this is something that all backpacks have nowadays, it’s not enough. You want to find out how good the water resistance is, how well the zippers resist water and if you can “lock” them shut.

Before buying one, try spraying some water on it and see if water seeps through any of its seams or openings.

Comfort – The next feature to consider is comfort. If you plan on using your pack for a long time, it has to be comfortable.

Some of the things you should look out for are adjustable shoulder straps and hip belts if they’re included in your pack.

Also, try wearing the backpack (without anything inside) and see how well it fits and adjust the straps accordingly.

Front Loading is a handy feature since you can access your stuff without taking out everything else. Some packs have it; others don’t. Just see if the pack you’re interested in has this feature or not.

Size – The last thing you should consider is how big or small of a pack you want to get. If you’re going to be using it mostly around home, it doesn’t hurt to get a smaller size.

If you’re going to be using your backpack for school or camping trips, then go with the 30-liter pack.

Compartments – The more pockets and compartments there are, the better. That means that your items will be easier to find, and you won’t have to carry around a big bulky wallet.

Also, see if it has a compartment for your laptop or not (some 30-liter bags don’t).

Padding – You want to make sure that the back of your pack is well padded, especially if you are not planning on using another bag or backpack. Your shoulders will thank you for it; make sure it’s not too bulky.

Price – Before buying anything, always compare prices to get the best available quality and affordability.

Those are the things you should look out for when buying a new bag like this before purchasing one! Hope I have helped make your decision easier!
