How to Choose the Right Size and Fit
Pick the wrong size and you'll be adjusting the straps all day. Follow these steps to get it right.
Step 1: Measure Your Torso Length
Get someone to measure from the C7 vertebra at the base of your neck to the top of your hip bone. This distance determines whether a pack's harness will sit correctly. For most adults, 15 to 17 inches is the sweet spot for a standard backpack. The Pro Gamer has a sternum strap that adjusts for shorter or longer torsos.
Step 2: List Your Daily Carry
Write down everything you take to class on a typical Monday: laptop, charger, binders, water bottle, maybe a small handheld console. Estimate the weight. If you're under 12 pounds, the Icon will work. If you're over that or you carry a 17-inch gaming laptop, go with the Pro Gamer.
Step 3: Test the Shoulder Straps
In the store (or when it arrives), put a few books inside and cinch the shoulder straps so the pack sits high on your shoulders. The straps should curve around your chest without digging into your armpits. If they wrap too tightly, the torso length is too short for you.
Step 4: Use the Load Lifters
The load lifter straps are the ones up by your shoulders. Pull them until you feel a slight lift off your shoulders. They angle the pack so its weight presses against your back instead of sagging toward your hips. This is the adjustment most people skip, and it makes a huge difference.
Step 5: Walk Around for Five Minutes
Don't buy a backpack without wearing it for a few minutes. Load it with 10 to 15 pounds and walk around the store. Watch for sliding when you lean forward. If the hip belt is doing the work (about 20% of the load), you're good.
