Above all else, the best backpack for you is the one that fits your body the best. One of the keys to finding that right backpack is to get one that is the correct size (e.g., small, medium, large). Your torso length—not your height—is the key measurement. Your new backpack has several straps to adjust your load for greater comfort. Your legs have some of the strongest muscles in your body, so the goal is to adjust your straps so that the majority of the load rests on your hips. We can help you do that!
