We all have unique body types, so two people of the same height may be better suited to two different sizes. That's why it's important to measure the key dimensions and choose according to your own measurements.
STEP 1: MEASURE YOUR TORSO LENGTH
C7 VERTEBRA TO ILIAC CENTER
Grab a measuring tape. Tilt your head forward to make it easier to and find the highest protruding knob at the base of your neck. Ahoy! It’s your C7 vertebrae—the starting point for your soft measuring tape. Tilt your head back up and run the tape straight down your spine until you reach your Iliac Center. This is the point in the center of your spine that aligns with the highest point on your hipbone.
STEP 2: PICK YOUR PACK!
Once you know your torso length, you can find out which size you should buy in whichever Gregory pack you like. And remember, all Gregory packs are sized the same regardless of gender, so a medium is a medium whether it’s unisex, a men’s pack, or a women’s pack.
STEP 3: TRY ON THE PACK
We always recommend throwing at least 4,5 - 9,0 kg in the pack. From there, the most important thing you can do is make sure the top edge of hipbelt is sitting 2.5cm above your iliac crest shelf. Next, the shoulder straps should wrap smoothly over your shoulders and should start wrapping onto your back, about 8 cm below the top of your shoulders. If your shoulder strap starts lower than 8 cm, try a larger size.
