  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 Very nice The liquid will be at the same temperature for some hours. It is very important to fill the bottle with a drinkable temperature, because if You fill in a very hot liquid, You don't can drink it after one or two hours!

Rated 5 out of 5 by from Buried Treasure I found this Hydro Flask in my attic buried under my camping gear, hunting gear and snowboards.... I sure this is one to the OLD ONES! I have fond memories with this Hydro Flask; I remember this flask helped me stay alive at Mammoth Mountains when I got separated from my team. I stored "SCALDING HOT" tea inside before the excursion. After 5-7 hours later, the tea was still hot! Kept me warm....
