  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 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 Perfect for hot/ cold water Love my hydro flask! Finally, a product that does exactly what is says.

Rated 5 out of 5 by from 2nd go around This is my second identical hydro flask. My first was really beat up and battered. Then I lost it. I was lost without it. I ordered another identical one. It goes everywhere with me. They are really great.

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.

Rated 5 out of 5 by from My daughter loves it I absolutely love this product. Was purchased for my youngest daughter, who hates drinking water but now that she has this, she loves to carry it around and is actually drinking the water.

Rated 5 out of 5 by from Great Features my sister got this for my birthday and its the best water bottle for volleyball. Also it keeps it cold for a long period of time.

Rated 5 out of 5 by from Awesome water bottle! I bought this for my very active 8 year old son. He does a lot of outdoor sports and this bottle was perfect for him. His water has to be cold and this bottle does the trick on those hot summer days. I will be purchasing him a much larger bottle when race season kicks back up, this one is good for long bike rides and sports that don't last all day.

Rated 5 out of 5 by from Fantastic cold! I bought this after trying Tervis’s, regular water bottles, etc etc., and finding them all lacking in one way or another. My Hydro Flask is officially the last water bottle I will EVER buy.

Rated 5 out of 5 by from Great gift! Grandchildren loved their water bottles. Healthy gift encourages drinking water that is a lot gentler on kidneys than surgery drinks.

Rated 5 out of 5 by from The Bottle! Was a birthday gift for my 8year old daughter she loves it!

Rated 5 out of 5 by from I drink so much water now! I used to always have a glass of water beside me, but I never noticed that I progressively drank less water as it started to warm down to room temperature. My Hydro Flask keeps it super cold for so long, I've started drinking so much more water. Love the design, love the durability and the materials, I don't think I'll ever buy another brand again.

Rated 5 out of 5 by from Nice product My 11 yr old granddaughter specifically asked for the yellow flask & boot for her birthday 3 weeks ago. When she visited us last night she was carrying the flask filled with water, which she loves to drink. She’s very pleased with it.
Date published: 2020-04-06
Rated 5 out of 5 by from it’s such a good water bottle! i bought this a month or two ago and i am so happy i did i love it so much you may be wondering if it is worth the price and i think it depends because honestly you could just get a flask and the only thing that would be different was that it wouldn’t have the hydro flask logo it’s up to you but it’s a good bottle i use it for my school!
