  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 Amazing thermal insulation! This is, without a doubt, the best water bottle that I have ever used. The wide mouth allows you to add ice cubes, sliced fruit, or whatever else you desire to your water, and the top screws on tightly so you can bring it anywhere with you without worrying about spills. The flexible silicone handle also makes it easy to carry around in your hand, although I would probably recommend getting a bottle sling if you want to attach it to a bike or something. For such a huge capacity, the size really isn't that bulky, and the fact that you don't need to refill very often makes it super convenient and simple to stay hydrated. However, what really amazed me about the HydroFlask was how well it insulates my drinks! I can throw in a few ice cubes, fill it up the rest of the way, and the liquid inside will stay cold for hours as long as the lid is screwed on. I've tested it by leaving it at room temperature for over twelve hours, and there was still frozen ice inside when I checked. The only downside I've noticed is that if you fill it up too much and there is a lot of ice inside, a vacuum somehow forms inside the bottle that makes the lid very difficult to unscrew. I'm not sure how or why this happens, but it probably has something to do with the air at the top of the bottle becoming denser at a lower temperature. That said, it's not that difficult to avoid, and the fact that it happens at all is a great testimony to how tight the seal on this bottle is. Grab one, you won't regret it!

Rated 5 out of 5 by from Recommend product Definitely a great product, use it with the flip straw lid. It keeps my drink cold with making my hands cold and taste is untainted. I have yet to drop it so I don’t know how durable they are but I bought it with the mindest “if it gets dented oh well”. Would definitely recommend

Rated 5 out of 5 by from Perfect color, perfect weight perfect size! LOVE my new wide-mouth (with a straw) Hydro Flask! I love the color, it's easy to carry, easy to clean, easy to drink from.

Which flask fits in a car cup holder?&nbsp;

Asked by: ChiShan412
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).
