  1. 1. Torso Measurement

    • A. Bring your chin to your chest and feel for the most prominent bony bump where the slope of your shoulders meets the back of your neck. This is your C7 vertebra, and the top of your torso measurement.

    • B. On each side of your body, feel for the top of your hip bones, just below the sides of your ribs. With fingers pointing forward and thumbs pointing backward, draw an imaginary line between your thumbs. This is the bottom of your torso measurement.

    • C. Stand up straight and have a friend with flexible measuring tape measure the distance between your C7 vertebra and the imaginary line between your thumbs. That’s your torso measurement. If you are between pack sizes, go with the smaller size.

  2. 2. Hip Measurement

    While your torso measurement is the best indicator of your pack size, it’s still important to check your hip size when using a hipbelt. To find your hip measurement, wrap a flexible tape measure around the top of your hip bones, just below the sides of your ribs. This measurement is slightly higher than your waistline

Questions

I have the 32oz and it does not fit in the car cup holder. &nbsp;The 40oz looks slimmer, does it fit in the car cup holder?

Asked by: akestelle
The 32oz and the 40oz are the same diameter. If the 32oz will not fit in your cup holder, the 40oz will not either.

does the 40 oz bottle fit in a standard cup holder

Asked by: jjrr
Typically our 24oz flasks and smaller fit in most car cup holders. We recommend measuring the diameter of the cup holder and comparing that measurement with the dimensions of our flasks (located on the FAQ page on our website).
