  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 Worth the money! My husband loves his Hydroflask and takes it to work daily! Does not leak in the car, keeps his drinks cold and wide mouth to drop citrus in the water.

Rated 5 out of 5 by from Been a fan for years It’s great! I’ve always loved their flasks. The only thing is is that it’s really heavy once it’s full but I guess if it’s light or thin the fluids won’t stay cold or hot as long as they do. So, all is good with this flask! It helps me keep track of how much water I drink in a day. I got one for my boyfriend as well and he loves it for work.

Rated 5 out of 5 by from Love my hydros! Before purchasing my first hydro I struggled drinking the amount of water I should daily and having it on hand wherever I’m at makes it so much easier! I love ice cold water and it keeps my water perfectly cold for so long! It doesn’t hurt that it’s a super cute color and even cuter with all my stickers as well! :)

Rated 5 out of 5 by from Snapper is catchy! Snapper is a fun color and I like that I can get the boot and the lid in the same color. I really like the bright colors, it makes them easier to see when you are trying to carry too much and don't want to lose your Hydro Flask! I love this one!
