  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 A life changer! Everyone on my gift list received a Hydro Flask this year after I received one as a gift over the summer. Now my daughters won't drink out of any other water bottle! I sent my brother a Coffee Hydro Flask and my husband got a second Hydro Flask after someone swiped his at work! The only negatives are they are a bit heavy and pricey -- but other than that, the design is perfect. My youngest asked for a "big" Hydro Flask to replace her kid one because "she is going to be 8 in five months!" A life-changing product!

Hello :) The descr. says &quot;keeps cold for 24hrs, hot for 12hrs,&quot; however product video says &quot;hot for 6hrs.&quot; The lid shown in the video is also different, does lid type affect time for heat? Which lid comes standard with this 18oz? TY!

Asked by: rel1speed
The flasks will keep liquids hot for up to the 12 hours and cold for up to 24 hours. The flex cap this one comes with does better insulate because it completely connects to the flask with no openings.
