  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 Perfect I just had a baby and I already have a toddler. The bottle goes everywhere with me as a reminder to drink water. Also if it gets knocked over by my toddler, the water doesn’t spill out. Although I could use any water bottle, I like the design and the color I chose. Also, I trust the durability since I trust the Hydro Flask brand.

Rated 5 out of 5 by from Actually spill-proof for coffee I love it! The secure top actually allows me to put this into bags without being concerned about leaks/spills (I did many tests before trusting it). It keeps my coffee hot for hours and I will definitely be traveling with it for the holidays!

Do they float? I'm looking for something with a closed lid to use on my kayak and with the possibility of flipping the kayak I would like to make sure I will be able to locate the flask if that were ever to happen.

Asked by: Pat G
Hello, I do apologize about the longer response time! No, with the flask being filled they would not float. They may float if they happened to be empty at the time but I cant guarantee that.

Are any of the water bottles&nbsp;dishwasher safe?&nbsp;

Asked by: SEO1
According to the Dick's Sporting Goods packaging my 24 oz small mouth i just received is dishwasher safe? Amazon is also reporting they're dishwasher safe. But I see no marking on the bottom that says it's dishwasher safe. Please explain

I am getting a metallic taste in my water from the 21 oz flask. I&rsquo;m surprised as it has 18/10 stainless steel. Is there anything that would get rid of this? &nbsp;

Asked by: David Werner
We understand how frustrating treating odors can be, but we have a quick trick to battle the issue: Mix 2-3 Tablespoons baking soda with a small amount of warm water to form a paste. The paste is a nonabrasive scrub and deodorizer. Rinse the flask with warm water. Then wash with regular dish detergent.

Can I use the lid with the straw for coffee in the standard mouth 24 oz bottle

Asked by: Reacher
Our Wide Mouth Straw Lid is compatible with all of our Wide Mouth Bottles. Unfortunately, the 24 oz bottle is a Standard Mouth and is not compatible. We have our Standard Flex Cap and Standard Sports Cap that will fit the 24 oz bottle.
