      Rated 5 out of 5 by from Love this product!! I bought this for my son for Christmas. ( He said Mom, I want a Hydro Flask). He absolutely loves it. He brings it to school everyday for his water. It stays cold all day! So happy i bought it.

      Rated 5 out of 5 by from A life changer! Everyone on my gift list received a Hydro Flask this year after I received one as a gift over the summer. Now my daughters won't drink out of any other water bottle! I sent my brother a Coffee Hydro Flask and my husband got a second Hydro Flask after someone swiped his at work! The only negatives are they are a bit heavy and pricey -- but other than that, the design is perfect. My youngest asked for a "big" Hydro Flask to replace her kid one because "she is going to be 8 in five months!" A life-changing product!

      Rated 5 out of 5 by from If you like your liquids cold! I asked for this product for Christmas, and got it! I wanted it as my workout bottle, because I love my water as cold as possible. I could not be more pleased with how cold and for how long this bottle works. So I highly recommend it. Don’t forget to buy the sports top to go with it!

      Rated 5 out of 5 by from Awesome waterbottle for anyone I bought this for my parents who do not like using reusable waterbottles. They love them! Have been using them most days and claim it keeps their water so cold. Plus, they love the sleek design and crisp colors.

      Rated 5 out of 5 by from Perfect for the student I heard a lot of varying opinions about hydro flask, but I got one anyway. So happy! Keeps my water cold all day and hot chocolate warm in the winter. Only bad thing is it dents pretty easily and dirt sticks to it really easily. It still works very well though. So if you're looking for a good water bottle, go with HYDRO FLASK!!!

      Rated 5 out of 5 by from Perfect Fit for Mouth. Perfect Fit in Lunch Box. This is actually one of four Hydro Flasks I own which I am providing a review. The two most recent (includes the one being reviewed) are a perfect fit for my mouth and also fit very well inside my lunch box. Did I mention how cold (or warm) they keep the beverages? That part is perfect as far as I'm concerned. My other two Hydro Flasks travel with me on my motorcycle trips throughout the Southern US and cross country. Every Flask is quite durable and I have recently purchased 6 more as Christmas Gifts.

      This is not a question we can answer since that is not our product. We recommend you take your pack to one of our local retailers to test this for yourself!

    1. Torso Measurement

      • 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.

      • 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.

      • 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. 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
