Decide which size of the Tortuga Travel Backpack—40L or 30L—is right for you.

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

The height-adjustable, gender-neutral 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.
