  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 Always a Winner! This brand of water bottles has never disappointed. Keeps my water cold all day. And if I use ice, sometimes I have ice in it the next day. Only great things to say about it. This size is a perfect size to pop in my bag and go. Haven’t tried it for hot drinks but I’m sure it would work just as well.

Rated 5 out of 5 by from Superior quality! I absolutely love the Hydro Flask 21 oz Standard Mouth Bottle with Standard Flex Cap, Laguna! It is the perfect size to contain an ample amount of either hot or cold beverages, and a Small Tag Along Bottle Sling is also available for portable convenience. I’m especially impressed by its ability to keep cold drinks icy cold and hot drinks piping hot, while being lightweight, yet very durable. The lifetime warranty against manufacturer defects seems unnecessary since the construction and design appear to be extremely long-lasting. I’ve already carried it along for both hiking and biking, and it can fit into a vehicle cup holder for easy transport as well. The superior quality of its easy grip, sweat-free coating and pro-grade stainless steel are exceptional, plus I really like the sleek style and bright color! It is simple to drink from and easy to clean by hand, although it is surprisingly dishwasher-safe. Now that I’ve been using it for both cold water and hot coffee, I completely understand why the bottle is a best-seller! I would definitely recommend this product, and it has instantly become my new personal favorite!

Rated 5 out of 5 by from Love!! I’m obsessed! My new favorite water bottle. I was bummed it didn’t come with the straw cap and had to buy it separately but I still couldn’t be happier!

Rated 5 out of 5 by from Works Good This is my families 3rd Hydro Flask, these things are very handy, easily stored and carried and keeps drinks cold. These are perfect for road trips, day hikes, sporting events, or just about anything else. These are well made and sturdy. Haven't found any defects or flaws. Well made product.

Rated 5 out of 5 by from Love love! I LOVE this water bottle. It is so easy to drink out of and keeps my water cold. The lid screws tight and I like that it has a convenient little handle on the top. Also, the turquoise/aqua color is beautiful!!

Rated 5 out of 5 by from Quality Bottle I got this bottle that replaced a cheap plastic bottle at the gym. Initial impression is that this is a quality bottle that feels great while holding it in your hand. The stainless steel inside is much more healthy and easier to keep clean in the long term. The best feature is that this bottle will keep your drink cool or hot depending on the drink. Hydroflask is a quality that is hard to beat and I will continue to use this brand in the future.

Rated 5 out of 5 by from Cute water bottle ! This is seriously the prettiest blue water bottle. Cannot go wrong with the quality if a hydro flask. Fits perfectly into the sling that you can get as well. Keeps my drinks very cold for hours. And the bottle is super durable. Love it !

Rated 5 out of 5 by from I need to buy a house-full. I LOVE to have an ice cold beverage. I have tried so many different water bottles over the years and I have gotta tell you, this one takes the top of the cake. I put nugget ice in this and the next day I still have nugget ice and an ice cold beverage. I can't wait to buy an even bigger bottle!! Worlds best water bottle.

Rated 5 out of 5 by from Wonderful for school My child needed a water bottle for school and she pick this one and she liked the color. We also have the small tag along bottle sling. We do have other Hydro Flask products so we knew we would not be disappointed. It is dishwasher safe but it is better to hand wash. We like it because your beverage either hot or cold stays that way for a long time. It is made out of stainless steel and double wall installation. It is a twist on top with a small handle which is a little hard to carry.

Rated 5 out of 5 by from Awesome My daughter has always been a huge fan of the Hydro Flask and continues to collect as many as she can. When I saw this one, with the carrying case, I knew she would appreciate it. She absolutely loves it. At first I thought she would prefer to carry it in her backpack, but I was wrong. She loves the carrying case. Game changer.

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.
