Outbreaker Backpack Size Guide

Decide which size of the Outbreaker Backpack—35L or 45L—is right for you.

Both sizes of the Outbreaker Backpack are designed to fit nearly everyone.

The height-adjustable suspension system adjusts to you. Move the shoulder straps up or down to find the best fit for your body. Adjust the hip belt for a snug fit to take the weight off of your shoulders.

With a comfortable fit, you can then choose the right size backpack based on your travels and packing style, not your body.

Best For:

Budget and European Airline Flyers
If you frequently fly on European or budget airlines, consider the Outbreaker 35L which meets stricter international carry on limits. We’ve flown on budget airlines with the 45L without issue, but it’s technically over the size limit on some airlines.

Minimalist Packers
If you’re a light packer, the 35L is for you, no matter the duration of your trip.

Best For:

Long-Term Travelers
If you’re packing for a long-haul trip, the 45L is probably for you. You’ll have enough room to bring everything you need for months—or years—on the road without checking a bag.

Max Packers
If you’re new to traveling carry on only or like to bring a little more than just the bare essentials, the 45 is the right bag for your packing style.

How to Measure Your Torso Length

Start by measuring your torso along your spine. Use a soft tape measurer and ask a friend to help.

Bend your head forward to find the vertebrae that sticks out at the top of your spine. That bone is your C7 vertebra. Start your measurement there.

Place your hands flat at the top of your hip bones with your thumbs pointing towards your spine. Use your hands to create a "shelf" that your backpack will rest on.

Have your friend measure from your C7 vertebra to the shelf you made with your hands. That distance is your torso length. Compare that number to the torso lengths above.
