  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 ask a friend to measure the distance between your C7 vertebra and the imaginary line between your thumbs using a flexible measuring tape. That’s your torso measurement. If you are between pack sizes, go with the smaller size.

  2. 2. Hip Measurement

    Although 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 Hydro Awesome My 1st experience with a hydro flask was when my granddaughter got one for me as a gift. I loved it, carried it everywhere, then someone stole it from my cart at the supermarket. A small distraction and just like that it was gone. I had to buy another, I couldn't get the same performance from other water bottles I have at home. #happyonceagain

Rated 5 out of 5 by from A favorite every time! I ordered two smaller flasks a month ago, and immediately came back for two larger flasks and one for coffee. A favorite every time!

Rated 5 out of 5 by from The perfect size I bought this bottle for my wife as a Mother’s Day present along with the sunflower boot and pink lid. She loved the colors together and the bottle is the perfect size. She has had a lot of trouble in the past getting dehydrated from not drinking enough due to as soon as a liquid gets slightly cool rather than cold she stops drinking it. There is still ice in the bottle a day later and she drinks two or three bottles full a day now. I am very happy that I made the purchase for her and she loves it as well.
