  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 Good Quality Am so satisfied with this product, definitely recommended… I have it with me wherever I go
Date published: 2021-09-08
Rated 5 out of 5 by from We love ours! After a recommendation from my niece, I bought 2 of the standard mouth along with the spout lid a few moths ago. We decided to stop buying bottled water. We loved them so much that I bought 2 more just recently. We use them almost every day. They keep a drink so cold that there is still ice in them the next day.

Rated 5 out of 5 by from Worth it ! I bought this bottle 5 years ago during my journey in Bend, Or. Ever since, I have been using this bottle for either a daily use or during my trips. It's easy to use and to refill that's why I like it ! The negative note is that the cap broke after 4 years (still good). To finish, in my opinion the 18oz is not big enough for some situations.

Rated 5 out of 5 by from I love Hydroflask waterbottles! My son got a Hydro flask water bottle as a gift, and he uses it all the time. we live in the Utah desert and he left his water bottle in our car in over 100° heat for three hours. when we got back to the car he opened it up took a sip and surprisingly the water was still slightly cold. these are fantastic at keeping your liquids cold in hot temperatures. I went ahead and bought three more for my other kids. These water bottles are amazing for hikers in hot temperatures! I love the small ones too because they’re light enough for my kids to carry. I highly recommend the Hydro Flask water bottles.

Rated 5 out of 5 by from Perfect I received flask about a month absolutely love it. My favorite aspect is the color.....I choose yellow. The flask keeps the water even colder then I expected. So thrilled to did my part for the environment and not purchase plastic water bottles.

Yes, milk shakes should be fine! We would just suggest taking extra care with cleaning after putting anything besides water in the flask.
