How to Choose a Pack Size

Your torso length, not your height, determines your pack size. We recommend the following to determine yours:

  1. Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
  2. Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
  3. Place your hands on your hips so you can feel your iliac crest, which serves as the “shelf” of your pelvic girdle. (It’s the first hard thing you feel when you run your fingers down from the sides of your ribcage.) Position your hands so your thumbs are reaching behind you.
  4. Have your friend finish measuring at the point where the tape crosses an imaginary line drawn between your thumbs. This distance is your torso length.
    • Small (15.0” - 17.0” torso)
    • Medium (17.0” - 19.0” torso)
    • Large (19.0” - 21.0” torso)
    • Tall (21.0”+ torso)
  5. If your measurement falls right in between sizes (for example, if you have a 17.0” torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.

Enjoying the pack!

The Junction 55 is a great backpack. I won't typically use it for over 30 lbs, but under that it has proven to be very comfortable. Above 30 lbs, it seems to pull a bit heavy in the shoulders, neck. I'm between 5' 9" and 5' 10" and have a 19" torso and went with the large size which seems perfect. I've had a bit of tearing of the mesh in the back, so it needs to be handled kind of carefully.

The BEST pack!

Good size! The front mesh pocket is my favorite. I do need an expert to teach me how to pack it-but Hyperlyte is definitely my favorite backpack!
