  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 Feels nice, Keeps water handy. Was skeptical on buying, I don’t regret my purchase. Needing to drink more water, I bought this 40 oz. water bottle to fill with my big berkey water purifier to keep nearby. So glad I did. Easy to clean, easy to fill. Easier to drink more water. No need for bottled water. Life is good :) It keeps my water from getting warm and stale. Everyone deserves to be hydrated and pampered with a nice quality water container that is esthetically pleasing to the eye and feels nice to the touch. And keeps my beverage from getting warm in the hot summers or turning into ice in the colder months.

Rated 5 out of 5 by from I Love This Bottle! This is a great bottle. I have it with me all of the time. It keeps my water cold. I prefer the lid with the straw. I have bought so many of these. I sent one to each of my children and a smaller one for my 4 year old grandson.

Rated 5 out of 5 by from Worth it I bought this a couple weeks ago and was excited to see what the hype was about. I love my hydro flask, it keeps my water fresh and cold.

Rated 5 out of 5 by from Best Bottle Ever!!! I bought 2 of these several years ago. Unfortunately, they got misplaced when I moved. I finally put my hands on one of them and began using it. I have NEVER been so impressed with a product. I filled it with ice and water at 6 PM last night. It is now approximately 1 PM the next day. I was shocked that the ice was still intact, so I took a sip. Cold enough to give me a brain freeze. 19 hours later!!! You totally need this bottle!!!

Rated 5 out of 5 by from the only bottle brand I’ll ever use again This is my second hydroflask - nothing was wrong with my first one, I just needed a color update. I take this bottle literally everywhere with me, and it continues to look brand new even after continuous active use for a month. I don’t think I can use another water bottle ever again.

Rated 5 out of 5 by from Nice size! I thought the 40oz would be too big to carry around but it’s the best size! I don’t have to refill it all the time and the water always stays refreshingly cool!

Rated 5 out of 5 by from Amazing Purchase!! I bought this product almost a month ago and J have feel in love with it. At first I did understand the hype of a hydro flask until I tire it out. And just wow my water has never tasted any better!! Keeps my water cold for extended periods of time the quality it just phenomenal I can’t tell how many times I have dropped it and the color on the water bottle had yet to chip or dent.

Rated 5 out of 5 by from The Greatest Gift Everyone in my family has their flask EXCEPT dad and it was time for him to join the club! He had a problem with getting dehydrated during the day because he was just refilling little water bottles with tap water. Now he fills it three or four times a day with ice and water that stays cold and he hasn’t been dehydrated since!

Rated 5 out of 5 by from worth it! At the price I was pretty hesitant to buy this water bottle BUT so far it is super worth it! It's a hot summer and all I want on my long walks, beach days, just being home, is ice cold water and this has 100% delivered. Plus it doesn't condensate on the outside at all, so my bag doesn't get wet. If you want cold water for hours, even when the bottle is sitting in the sun - I'd invest in this. It is heavier than other bottles though, just FYI.

Rated 5 out of 5 by from The Best Creation I bought one a month ago and really liked it, so I bought one for my sister. She really loves it and can’t imagine going back to her other water bottles.

Rated 5 out of 5 by from Love my hydro So happy I decided to order a bigger hydroflask (previously having an 18oz.) makes me drink more water while having it not feel like I’m doing so with the larger size. I heavily recommend buying a straw lid with it too makes drinking water easier and makes me drink more as well.

Rated 5 out of 5 by from Great features! I bought this about a couple of months ago for my boyfriend and he loves it. Keeps your water very cold. He loves that fact that he can take it with him on his workouts.

Rated 5 out of 5 by from Giftee absolutely loves I purchased this for my fiancé, who works as an electrician. He consistently raves about how much he loves it: well insulated, wide mouth, stays cold all day, easy to carry (I got him the carry sling too).

Recently I ordered my hydro flask and was super happy about it it did everything it was supposed to and worked great . I ordered the frost color and it was beautiful . I have on question though mine came without a trademark symbol by the logo ?

Asked by: Happy costumer
Newly produced Hydro Flasks do not feature a registered trademark symbol next to our logo. This decision was made to enhance the presentation of the logo on our bottles. The absence or presence of a Hydro Flask registered trademark or R symbol next to our logo is not an indicator of authenticity.

Does this typically fit in a car cup holder, I drive all the time so that would be a huge advantage&nbsp;

Asked by: Jessica3316
Typically, our 24oz flasks and smaller fit in most car cup holders. We recommend measuring the diameter of the cup holder and comparing that measurement with the dimensions of our flasks (located on the FAQ page on our website).
