  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 Great addition Works really well in the car while driving, always ready !

Rated 5 out of 5 by from Works great! We have had our Hydro Flask for several years. We love them. The sport cap is wonderful.

Rated 5 out of 5 by from worrying was pointless After reading some of the reviews about the product leaking, I was hesitant when it came to purchasing it without first seeing the quality for myself. Thankfully, I found them in-store and decided to give it a go. Since buying this, it has not leaked even a little bit and despite consistently chewing on the mouthpiece, there aren't any marks on it. Needless to say, the worrying I did beforehand was completely pointless.

Rated 5 out of 5 by from Love it! Love my new straw top! I am drinking more water than ever before!
Date published: 2020-08-26
Rated 5 out of 5 by from A great lid I have had the flask for years with the standard plug lid that you had to remove to drink from the container. I would take the lid off, and then lost it in the bottom of the car, or under my desk. This is perfect, I can drink from it, and the lid stays in place. Very happy

Rated 5 out of 5 by from Great Sport Cap! The sport cap is an ideal solution for my bottle. When it's closed, it doesn't leak and when I want to drink I can quickly pull the spout and drink without spilling water all over.

Rated 5 out of 5 by from So practical! I bought this about a month ago because I only had the cap that comes with a Hydro. I have been using this everyday after training and it is amazing! So much easier to use than the other lit and makes more sense as an athlete.

Rated 5 out of 5 by from Convenient and easy to clean ! Bought it recently. It’s nice to use when driving. No need to unscrew.

Rated 5 out of 5 by from AMAZING! I just got this! And it’s soooo perfect I love this totally recommend!!
Date published: 2020-05-01
Rated 5 out of 5 by from Handy item I have one as a secondary cap for my HydroFlask 750ml wine flask. Can pour into my Hydroflask cups or drink right from spout. Great for any beach or other location where "No Alcoholic Beverages Allowed"
Date published: 2020-04-22
Rated 5 out of 5 by from Works perfectly for my bottle! I bought my hydroflask in Wholefoods but it comes with the regular cap. So I had to order this one. The water comes out very well. Highly recommended!

Rated 5 out of 5 by from Great lid Great top, makes you drink more water and still you can carry it...

Rated 5 out of 5 by from Love it Great fit, works well. Its nice not having to deal with the straw issue.

Rated 5 out of 5 by from question I love this lid but it said that it needed a straw in the manual that it wass includded
Date published: 2020-03-14
Rated 5 out of 5 by from Excellent accessory. Saves a lot of money I previously bought a a hydroflask bottle, that had the twist on top with the handle. Over the years of me having it, it eventually became my water bottle. But, the top that it came with wasn't the best for water (well the actual bottle itself was the issue - the hole is kind of too big, so water will most likely spill while drinking). I was going to buy an entire new bottle, but then I saw this on the website, and I noticed it fit the type of bottle I had so I got it. It works amazing and makes my bottle an even better water bottle because it can keep the water cool and it's easy to drink from. It works like any other (push,pull) top. The only thing you have to look out for is to not get the top dirty, because there's nothing covering the top.

Rated 5 out of 5 by from Question Can this be used for the top cap on the 128oz bottle? Cheers
Date published: 2020-02-21
Rated 5 out of 5 by from Nice quality! I bought it 4 days ago and it just came in the mail! it is great quality and is much quiet than the regular cap!
Date published: 2020-02-03
Rated 5 out of 5 by from A gotta have The cap that comes on the Hydra Flask 18 oz standard is a great cap. But this standard mouth sport cap is so much more usable in most instances. If you have to pick up the Hydra Flask and drink with one hand, you NEED this cap!

Rated 5 out of 5 by from Love it It is so helpful not spilling. It is better for sports than the normal cap.
Date published: 2020-01-02
Rated 5 out of 5 by from Love this thing! I was admittedly a bit nervous to buy this after reading some of the reviews, but I’m glad I did. It’s so much more convenient to drink out of than the normal flex cap, and I haven’t had a single leak when it’s screwed on properly.

Questions

does this fit the 32 oz?

Asked by: katelync3171
No

Do you need to suck on it to get the water out or does it just flow out 

Asked by: Scharpenburg
The standard mouth sports cap. You will tilt the bottle and use it as a straw. The suction is what opens the gasket to allow liquid to flow through.
Answered by: Consumer Service
Date published: 2020-02-05

Do you offer replacements for the little rubber valve/vent? My daughter’s is missing and it’s causing the bottle to leak far more than normal. 

Asked by: EBG913
At this time we do not have the gaskets available separately. However, we'd be happy to replace your cap for you under our Lifetime Warranty. You can fill out a warranty claim here: (http://www.hydroflask.com/warranty/)

Can you add a straw to it? Or is it just for the cap?

Asked by: AnnaBear123444
Our Standard Mouth Sports Cap does not have a straw attached to it. It has a spout that you open and close.
