  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 Great bottle! I love my hydro flasks! My most recent purchase was the 40oz bottle. I love the colors and the extra space over the 32. My only complaint is the paint seems to stretch pretty easily

Rated 5 out of 5 by from Best Water Bottle Ever!! I own a few Hydroflasks now and they're the only water bottles I've found that can actually keep my drinks cold throughout the day - even the ice stays cold for hours! They have amazing colors and I've fully eliminated plastic bottles from my routine. I hope everyone has one in the future so we can cut back on our plastic waste!

Rated 5 out of 5 by from Cold all day! I drink a lot of water so I’m very picky about my water bottles and this one lives up to my standards. Keeps my water cold all day and is the perfect size if you also drink a lot of water. Worth the price in my opinion. Beautiful color as well!

Rated 5 out of 5 by from Happily Ever After I am absolutely obsessed with my new Hydro and Straw Lid (v important addition). We are inseparable at this point. We go everywhere together: we go on hikes together, eat together, study together and sleep together. They keeps me hydrated and takes care of me. I never feel alone during quarantine now. Worth the hole in my wallet. DM for marriage invitation if I ever get a job to afford one during this crisis. Im actually not mad about this because everything is alright when I am with my hydro flask.

Rated 5 out of 5 by from Keeps all liquids really COLD!! I really like the wide mouth! It makes it sooo easy to just drop in big ice cubes. It also stays cold for up to 36 hours!! The only problem is that I ordered the Cobalt color and received the Black color?

Rated 5 out of 5 by from Still in love This is the second hydro I’ve bought and I’ve never found anything that compares. I use them everyday and they’re so handy.

Rated 5 out of 5 by from Meets all my needs and more! As a Firefighter/EMT working long shifts, often not getting back to station for hours at a time, having the Hydro Flask allows me to keep hydrated and ultimately refreshed. Best tool in my bag, I don’t go anywhere without it!!! EMT-B DFW/FTW Texas

Rated 5 out of 5 by from Love!! I bought this 40oz hydro to replace my 21oz and I'm obsessed! I drink so much water and had to fill my other bottle up so much throughout the day that I decided it was time to size up, and I'm so glad I did. Now, I don't have to try and find a water fountain on campus or run back to my dorm in between classes to fill up, I'm good for a few hours. I highly recommend also purchasing a straw lid, it makes it super convenient to drink when walking, driving, or trying to be quiet in the middle of lecture.

Rated 5 out of 5 by from Great I bought this about a week ago for my dad just for his work and for the sports he does. He loves it, it keeps ice all day and the color is amazing he says. It is very functional and very versatile and I would recommend to anyone looking for a new great water bottle fro their daily lives!
Date published: 2020-10-07
Rated 5 out of 5 by from Excellent! Since buying this product over a month ago, I have better kept myself hydrated. The bottle is durable, functional, durable, and beautiful. The boot is a nice add-on feature for extra protection, no condensation, and less noise when placing the bottle on a hard surface. 10/10 would recommend!
Date published: 2020-10-07
Rated 5 out of 5 by from LOVE LOVE LOVE I purchased this a month ago and I do not regret it! The color is slightly lighter then the picture but I am in love! It also holds the perfect amount of water. Would definitely buy again!

Rated 5 out of 5 by from Love my hydroflask! This 40oz bottle and straw lid have helped me drink more water per day than I ever have before. I absolutely love it! I have convinced 2 family members to get their own and they love theirs too. It functions as described and is nice and sturdy. I highly recommend the straw lid too!

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.

Does the straw cap fit the 40oz bottle? Does the straw reach all the way to the bottom of the 40oz bottle, as it would function regularly in the 32oz bottle? Or is it too short? If so, are there longer straw attachments?
