      Rated 5 out of 5 by from Hydro Flasks for Underwood & Rosenblum Our Hydro Flasks arrived a couple of weeks ago and our employees are enjoying using them. This is one product that actually lives up to its claims. Way to go, Hydro Flask!

      Rated 5 out of 5 by from Durable and cute colors! I’ve been purchasing Hydroflasks for years, and recently bought my first 40 oz! I love that it holds so much water but isn’t too clunky or bulky. The colors are unique and I’ve dropped mine a few times (oops!) and it’s still in great shape!! Highly recommend getting the straw top separately for those times when you don’t have to carry it around long, but want an easy way to drink your water!

      Rated 5 out of 5 by from Sturdy and Efficient! I honestly gasped at the price but my daughter loves it. We live in AZ and she needs something to keep her water cold for hours. This does the trick!

      Rated 5 out of 5 by from Loved it I bought this for my niece for Christmas and she loved it, she started using it right away. I'm glad I bought the sport cap to go with it, definitely needed with a flask this big.

      Rated 5 out of 5 by from 40oz bottle I've been a fan of Hydroflask for a decade now but these 40oz bottles have been the greatest addition to any pack. I've used it as I was a wildland firefighter perfect size to carry on the fire line. And I also use it now working on an ambulance as a paramedic it fits right into the built in cup holders. Holds ice for over 24hrs. The different attachments make it more adaptable to any situation. I like the straw lid since I'm always on the move I dont have to worry about trying to drink while my partner is driving or even on a hike I can keep moving. Bought this for myself and one for a gift and they loved it! Wouldnt trade it for any other bottle.

      Rated 5 out of 5 by from Great Gift! I was introduced to Hydro Flask by a coworker. I ordered 2 pieces for myself. Enjoyed them so much that I chose to give as gifts. My husband is very much enjoying the 32 oz wide-mouth.

      Rated 5 out of 5 by from Works amazing! This is the first size bottle I got. I now have 8 bottles. I got it for work. I am a lifeguard on the beach in Florida and sit in the sun for 8 hours a day. I can fill this bottle with water in the morning and there will still be ice when I refill in 4 hours later. I have been using this bottle for 3+ years and it still is in great shape even though it has been dented and dropped tons of times. Well worth it!

      Rated 5 out of 5 by from Amazing everything I expected I’ve bought this maybe a lil over a month ago and it’s perfect. I’m a heavy water drinker so this was a must for me. 10/10 if you’re having doubts about buying one don’t. It is on the pricey side but it’s completely worth every cent.

      Rated 5 out of 5 by from Best water bottle EVER! I received my HydroFlask as a gift several years ago and it went with me everywhere! I dropped it a few times and it became dented and still worked magnificently and became a permanent part of my life as it went with me everywhere! I measure my water consumption daily and this made it so easy. Unfortunately, I was hurrying to catch an airplane last week and my favorite companion, my Hydro Flask, got left behind at the gate! I asked the airline to try and find it but, I am pretty sure someone decided to give it a new home, and I am devastated! May it have a long and happy life with its new owner. I will have to get a replacement soon as I am lost without it!

      Rated 5 out of 5 by from A converted water drinker I'm so not a fan of drinking water (unless its freezing cold), so I did research and Hydroflask was the only way to go. I absolutely love my 40oz lilac water bottle!!! I bring it everywhere and I can't get enough water now. I find myself refilling it a few times a day. Especially since it keeps my ice frozen :). I'm converting everyone to water drinkers!!

      Rated 5 out of 5 by from My kid loves it! When my daughter told me she wanted a $60 water bottle, I thought she was crazy. Who pays THAT much for a water bottle? What in the world could make ANY water bottle cost that much? I asked myself these questions and more and realized, her mother would NEVER buy her this, so I did. I win! Score one for Dad! My kid loves me so much now. She walks around proud with her new Hydroflask and on a side note, she drinks plenty of water now and she stays hydrated, which is important.

      Is the wide mouth lid suppose to shed over time? I’ve had my hydro for over a year and now I am finding shards of my lid in my flask when I use it.

      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 

      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).

    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
