There’s certainly a number of factors to consider when selecting the appropriate backpack for your next outing or adventure. That can include size capacity, pack weight and you intended usage of that pack. When it comes to fit however, the starting point really should be taking your torso measurement and making sure you’ve got a pack with the appropriate torso fit range.
Taking your torso measurement is not difficult; in fact it’s pretty easy. It’s that much easier if you employ a second set of hands. Standing upright as you would as though you just put on your backpack and are ready to take off, lower your chin towards your chest. When you do that a vertebra will protrude from the top of the shoulders to the base of the neck, can’t miss it; Right here. Using a flexible tape measure, and that’s important, follow the spine, the contours of the spine, right down to a point that is even with top of the hip bones, the iliac crest. That’s important; the top of the hipbones and not further down the leg. As Liz is doing here, pointing her thumbs inward, that helps me identify exactly the point I should be measuring at the bottom of the spine and see a 17 ½ inch torso.
Keep in mind that torso sizing can differ in regards to backpacks in relation to torso measurement as it might be spoken of with clothing. Men’s torso lengths with backpacks often fall between 17 and 21 inches. Women’s, on average, maybe 14 inches to 18 inches but that range can differ dramatically, we’re all different. It’s important to actually take that measurement. Height feels like it should be a determinant and isn’t necessarily so. You could be 6’ 6” and be all legs with a short torso; 5’ 2” and have a longer than average torso measurement. Again, important to actually take that measurement.
