How to measure

Choose your pack size using your torso length.

  1. Tilt your head forward to locate your C7 vertebra, the prominent bony point at the base of your neck.
  2. Place your hands on your iliac crest, the upper edge of your hip bones, with your thumbs pointing towards your spine.
  3. Ask someone to measure along the curve of your spine from your C7 vertebra to the horizontal line between your thumbs at the iliac crest. This is your torso length.

If your torso measurement falls on a size boundary, Hyperlite recommends choosing the larger size.
