Yes, I know how to choose a backpack seems rather obvious. But . . .
Once you've taken your torso and hip measurements and decided which type of pack you want, you might be tempted to just get online, order the pack in your size and get on with planning your trip.
Don't. At least not yet.
Even a backpack perfectly sized to fit you might not sit well when it's on your back.
So, take your measurements down to a dependable outdoor gear outfitter with a decent selection of backpacks and check some out first.
Have a good look around to see what's available, then pick out a few packs in your torso length and hip belt size to try on.
First, you need to make sure that the pack you've chosen fits you properly. And to do this you'll need to test it out with some weight in it.
The best gear stores — the ones who know how to choose a backpack and fit it properly — will have sandbags for you to use. But if they don't you can easily make do with tents, climbing ropes, camping equipment or anything else that's heavy enough.
Distribute about 7-9 kg (15-20 lb) evenly inside the backpack.
Your actual pack will likely weigh a lot more when you're travelling, but this is enough weight for the bag to settle correctly on your back and for you to get a good sense of what it'll feel like once it's packed.
This step in how to choose a backpack probably sounds pretty self-explanatory as well. And to some extent it is.
But getting a fully-loaded pack onto your back can be a lot more awkward than you might expect, and you can really do a lot of damage to yourself if you're not careful.
The best way to put on a heavy pack is to set it upright on the ground and loosen all the main straps on the shoulder harness and hip belt first.
Then, you've got a few options. I'll save the easiest for last.
First, you can . . .
Or you can . . .
Or even easier . . .
But easiest of all . . .

You'll need to customise the fit of your backpack now by tightening, adjusting and fine-tuning all the straps.

Okay. Got the backpack adjusted?
Great! Let's move on.
Next comes one of the most important steps in how to choose a backpack.
Go for a walk.
Walk around the shop. Go up the stairs and down the stairs. Sit down, crouch down and kneel down. Stand up, jump up and jog a little. Lift your arms in the air and swing them around. Bend forward, bend back. Do a few cartwheels even!
Right. Decision time.
If everything's good it's time to hand over the cash.
The last step in how to choose a backpack is to take it for a trial run.
Fill your new backpack with as much stuff as you think you might pack on your around the world trip and bring it with you on a weekend away. Unpack and repack the bag a few times. Take it on a bus. Go on a hike.
If you're short on time, at least walk around your neighbourhood with it for an hour or two.
This is your chance to make sure your new backpack is perfectly fitted and that you know how everything works. Go back to the gear shop to get any problems sorted out and questions answered before you head off on your travels.
Congratulations . . . you've got a winner!
