  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 ask a friend to measure the distance between your C7 vertebra and the imaginary line between your thumbs using a flexible measuring tape. That’s your torso measurement. If you are between pack sizes, go with the smaller size.

  2. 2. Hip Measurement

    Although 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 Leak Proof Lid This Hydro Flask Wide Mouth Flex Sip™ Lid - Black fits my Hydro Flask 20 oz Wide Mouth. The handle is soft and flexible which makes it easy to carry. It's easy to take apart to clean and then put it back together again. All I have to do is twist the lid, take a sip then twist it closed. I can throw it in my bag and not have to worry that it is going to leak. This lid is a great addition for your Hydro Flask. I definitely recommend.

Rated 5 out of 5 by from Seal tight lid This lid worked really well with the cup. It's seal it really well and doesn't leak. The one thing that concerns me is that there are many pieces and I'm afraid they will tear or I will lose a piece, but I like that you can take it apart and clean every little part. This lid is also very comfortable the drink from so I don't have to unscrew it. Overall this is a good lid.

Rated 5 out of 5 by from Ice for Days I am really impressed with the Hydro Flask. I thought it would hold my water cold but I was wrong. It keep it super cold and ice for 36 hours. It was amazing. I had to refill my water before the ice. Love the color too.

Rated 5 out of 5 by from Perfect I ordered the hydro flask so of course I needed the lid....lol. It’s a perfect fit. Highly recommended. It fits and looks good which is a plus but not necessarily needed, as long as it’s functional. I get asked where i got it from.

Rated 5 out of 5 by from Love it Why did it take you so long to come up with this I can’t tell you how many times I would look in the mirror and see a brown spot on my nose from the other flip up lid so thanks for the new style I love it and I noticed it helps to better insulate my drinks!!!

Rated 5 out of 5 by from So much better than the flip top lid! I bought this to replace the flip top lid my hydro flask came with -purchased many years ago from a local coffee shop. SO MUCH BETTER! Easy to drink from, seems to resist leaking so far, & simple to take apart, clean & reassemble, once you get the hang of it! Well thought out design! My hydro flask is so much more enjoyable to drink hot beverages from now!

Rated 5 out of 5 by from Good Design So far I like this lid. I haven't had any leaking issues from it. I do like that it comes completely apart to clean it, so you never have to wonder if it's really clean. It does seal extremely well, which is great, except there's some splattering when you open to drink due to pressure build-up.

Rated 5 out of 5 by from Wonderful to hot drinks This is a great swap out when I'm using my Hydro Flask for my coffee or tea. I usually use it for water, but sometimes I use it for coffee or tea for work. This is much more convenient to sip from. It's really easy to take apart and clean.

Rated 5 out of 5 by from Love it This lid is a fantastic addition to an already amazing bottle. The lid fits all three of the bottles I own, and makes them even better and easier to use. Opening the spout is difficult at first, until you use it a few times and loosen up the action.

Rated 5 out of 5 by from Perfect! The flex sip lid is the perfect lid for the Hydro Flask. Love that I can adjust the hole smaller when handing it over to my youngest. It did not leak from the seal on the lid which was a definite plus. Perfect finish to the amazing Hydro Flask!

Rated 5 out of 5 by from Extra lid Back up top for my new hydro flask. It fits perfectly, easy to drink from, has a tight seal and doesn't spill. It's easy to wash. Even with being dropped the lid stood on. The handle on top makes it easier to carry.

Rated 5 out of 5 by from Perfect sip lip for our Hydro Flask This is a great option to use on our Hydro Flask wide mouth bottle. Just turn the sip lip and you have an opening to drink through if you don't want to take off the top. Perfect for when you are working out!

Rated 5 out of 5 by from Works Great The Hydro Flask Wide Mouth Flex Sip Lid goes on the Hydro Flask. It fits the flask perfectly and makes for a great experience while drinking . It is an absolute must if you have purchased the Flask. You can thoroughly enjoy any beverage with this set. I highly recommend these products.

Rated 5 out of 5 by from No leaking! I love this lid. The last tumbler I had with an open and close spout would leak if it fell over. This one does not leak at all! I can easily tell if it is closed or open. I work in a room where it is very important that my cup does not leak if it gets knocked over. I can enjoy my coffee again without fear of a mess. It is also nice that i do not have to always unscrew the lid to get a drink of coffee. I love the flex strap. It is easy to carry my cup when my hands are full. I have recommended this tumbler and lid to many.

Rated 5 out of 5 by from Nice lid I love this lid, there is no leaking even when my 2 year old gets ahold of my hydro flask and tosses it around! It keeps the temp of my drink regulated because it seals perfectly! I like having interchangeable lids for my hydro flask because depending on the drink I may need a different lid
Date published: 2020-12-11
Rated 5 out of 5 by from Heavy duty lid! This is a neat hydro flask lid. When you twist the top half of the lid it opens/closes the spout where liquid comes out so you can protect your drink contents when not in use. When in the closed position it also keeps your drink from spilling. The drawback for me is that the lip that touches your mouth when drinking is always exposed. It looks deceptively tricky to take apart and wash (8 steps to take apart and 8 to put back together), but after doing it once it’s no big deal. Each component comes apart for thorough cleaning, and it does have to be hand washed (which is kind of a pain), but to be fair it’s a pretty quick process. It’s a great solution for water bottle lid.

Rated 5 out of 5 by from Perfect for working out! I love my hydroflask for working out but hate taking the lid on and off. This one makes it easy to sip during bootcamp and when it's closed, it doesn't leak at all in my bag. Highly recommend for Hydroflask lovers!

Rated 5 out of 5 by from Really helpful I love this lid for my hydro flask really flexible and really easy to use for my cup to drink out of and easy to put on the cup plus this easy to clean and wash when your done with it I would say really great to use on the go or traveling

Rated 5 out of 5 by from Great accessory for my Wide Mouth flask! The Hydro Flask Wide Mouth Flex Sip Lid is a much needed accessory for my flask. It is leakproof, BPA-Free, and compatible with all Wide Mouth bottles. I love that it provides easy on-the-go sipping. Because of the pandemic, it’s only being used when working outdoors and exercising around my home to prevent airborne particles touching it. It provides a pain-free twist opening and is very easy to use and clean. I am very pleased with it so far. Also, I recommend it because it makes my bottle more versatile.
