  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 My New Favorite The Hydro Flask Wide Mouth Flex Sip™ Lid - Black is my new favorite drinking flask. It doesn't spill. It stays hot or cold for hours. I can look forward to a hit beverage remaining hot for a good 5-6 hours.

Rated 5 out of 5 by from Absolutely love it! Bought a month ago and worth every penny, I’m always on the go on the road and love that I don’t have to worry about it spilling just and easy twist and comes out with great flow

Rated 5 out of 5 by from Absolute favorite lid!!! I love my straw lid but this is even better!!! I use it on my larger wide mouth bottle for water. I love how is it designed to come apart so it can easily and throughly be cleaned.

Rated 5 out of 5 by from Coffee Adventure Just Got Better I have enjoyed adding this cap to my favorite 16 Oz flask. I like the handle. Makes carrying it a lot easier. The lid has a great seal. No worry about spills or leaks while carrying from place to place. A wonderful improvement over the original Cafe lid! So far have only used H2O in it. Due to the Stay at Home Order no trips to coffee shop. Instructions look as if the disassembly for cleaning and reassembly after cleaning will be a simple task.

Rated 5 out of 5 by from Combines best of different caps! Really convenient not having to unscrew the lid to drink. The carrying strap also corrects challenge on how to carry the 32 oz and higher volume bottles.

Rated 5 out of 5 by from GAME-CHANGER! Hydro Flask always made the best insulated cups, now they make the best lids too.

Rated 5 out of 5 by from So much easier Stops me swallowing a load of air when I chug my water so I don’t get bloated anymore! Can’t wait for more colour options, hope they release them in the uk :)

Rated 5 out of 5 by from Awesome lid I love that it had a strap so it’s easy to carry but a lid that I don’t have to take off to drink. Easy to take apart to clean and very easy to put it back together. Highly recommend.

Rated 5 out of 5 by from The best So much better than the straw. And easy to drink! Love this lid, now I have to order another one so my boyfriend stops taking it (:

Rated 5 out of 5 by from Exactly what I've been wanting This lid is exactly what I've been wanting. It comes apart easily for cleaning and just snaps back together. When it's twisted closed it does not leak all over my bag. It's great!
Date published: 2020-04-15
Rated 5 out of 5 by from AMAZING - FINALLY! Omg, I have been waiting for this lid for what feels like an eternity! It solves all the problems of the old wide mouth bottle lid. It is truly leak proof, it allows for one handed drinking, it is EASY to clean (no more perpetually dirty ring!), and still has a handle. I'll never go back--could not be happier with this purchase!

Rated 5 out of 5 by from So much better than the older ones! I’ve owned HydroFlasks since the beginning and I love them. My only real complaint has been the o-ring in the older coffee lids. This top seals the deal (pun intended). I love it and I’m not wearing my coffee. Yes!!!!
Date published: 2020-04-12
Rated 5 out of 5 by from The best lid!!! I love this lid, it’s leak proof and easy to open a and close. I use it on my coffee flask and my 32-40oz flasks. Great quality and hydro glad customer service is the best!

Rated 5 out of 5 by from Perfect I really love this and never had second thought for buying it because i know it will be perfect for my hydro bottle.

Rated 5 out of 5 by from Big Improvement on Old Lid A barista at the local coffee shop recommended this new lid to me. Unlike the old coffee lid, this one never gets coffee on my nose! Super convenient to have the strap as well, love this lid! Easy to take apart and wash as well.

Rated 5 out of 5 by from Love it! I so happy I ordered two! They are perfect...I’ve been using the straw lid version and was looking for something that was easier to clean!! And this was it! I will be purchasing a couple more once we get through this Coronavirus situation. Thank for making a great product!

Rated 5 out of 5 by from Love this lid I love that I no longer have to unscrew the entire lid off to take a drink and still have the handle. I was very excited to find this new lid and it does not disappoint.

Rated 5 out of 5 by from Excellent lid I love this lid so much! I’m drinking so much more water because of this lid! I love Hydroflask!

Questions

Does this lid insulate just like the wide mouth flex cap which is made with honeycomb insulation?

Is this compatible with the previous generation of coffee flasks?

Asked by: gilo1246
Yes.

Would you be able to use a straw with this lid?

Asked by: agnes28
Unfortunately, no. The mouth opening is not a hole that goes clear down. This is what helps make this product leak proof.

I’ve had this lid for about 2 weeks cleaning daily. This morning I cleaned it, put back together and is now leaking between the top and bottom pieces. I don’t understand what is different or if I lost a piece while cleaning?

Asked by: Problemmaker
We'd be happy to replace your cap for you under our Lifetime Warranty. Please fill out a warranty claim via our website: (http://www.hydroflask.com/warranty/). Once you’ve submitted your warranty, a claim number will be emailed to you within 2-3 business days.
