  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

Rated 5 out of 5 by from Drink without removing the cap! I love that I can drink from my bottle without removing the cap! I don’t have to hold on to a cap or set a cap down someplace while I drink from the bottle. It all stays together this way. So glad to be able to buy just the cap for a bottle exchange I had to make for a defective bottle & new replacement bottle came with a different cap that to me is useless. All reusable bottles should have a sport cap imo.

Rated 5 out of 5 by from Best option for hydration Helps My teenager stay hydrated easier. He needs to drink a lot for a medical condition. The screw cap did not allow for easy frequent drinking but this cap does the trick!

How do you open an close the valve for drinking on the sport cap? Are you suppose to pull something out or turn something?

Asked by: Fiddledave
Hello, Thanks for reaching out! I do apologize for the long response time! No, its just a pop lid. So you would just pull up the cap and then push it back down once your done with it.
