Hydro Flask Standard Mouth Sport Cap for Sale, Reviews, Deals and Guides

It is very convenient not having to unscrew the lid every time you want to take a drink. Would highly recommend.

Good cap, works good and is nice to not have to unscrew a lid every time but does leak a little-it does say it’s not leak proof. Overall I like the feature for my 24 oz.

Handy to use when outdoors, and makes it easier to drink from.

This handy lid is perfect for the gym or if you have little ones that you share with. Can leak and I've had some get a little noisy which can be embarrassing in a quiet place, its almost a whistle. Overall, its a winner and I highly recommend.

Son loves having this on his water bottle, especially for soccer when he runs off field for a quick drink

Great leak proof options that adds ease to your Hydro Flask.

We've had a few of these caps, one was replaced but they all eventually leak. The Hydro Flask bottles and cups are awsum for keeping liquid temps but this cap will leak. Heres a screen shot from the Hydro Flask website. It states they are not leak proof. If your not worried about leaks, which in some cases I am not like when its just water and its upright in my car, this cap works great! Just don't turn the bottle on its side or upside down !

This lid makes getting a quick drink during a workout much easier. Easy to use with no spills.

I bought a great HydroFlask a couple of years ago to take out climbing with me and specifically chose the 20oz one that was nice and narrow to fit in my Jeep's cupholder, figuring this would make it more convenient to use, and perhaps provide the incentive to actually drink more water, already. Turns out that I still didn't find the water bottle that user-friendly because it requires two hands to open the thing, one to hold the bottle and one to screw off the top. I noticed this sport cap on a display bottle and thought "Genius!" Picked one up at Backcountry at the first opportunity, and have literally doubled if not tripled my water consumption since purchasing it - it's so much easier to use that there are just no excuses anymore! Totally leak-proof even when left upside-down in my bag, this cap is never leaving my HydroFlask again :)

i love this option of cap if you dont want the twist off. Perfect for the quick, on the go person. No spills and pretty sturdy.

I bought my wife a hydroflask but it came with just the standard lid. I got this new cap at her request and it works great. It was exactly what she was hoping for.

This lid is a must have upgrade from the standard lid that comes with hydroflasks, It makes it alot more convenient to grab a drink instead of unscrewing the lid every time and is much easier to drink out of while on the go or driving and not having to worry about spilling. Still easy to carry with the loop on it as well.

It's easy to use and helps drinking out of your Hydro Flask easier, avoids spills all over yourself.

Works great

Great cap! It lets in plenty of air so it doesn't feel like you're trying to drink through a cocktail straw. The only issue I had was that if I did not press the lid fully closed, then it would leak, and the margin of error is pretty small. Otherwise, it is a great cap, and very ergonomic to use as a carrying handle.

Convenient not having to unscrew the lid to take a sip whenever, but can leak. Especially if bouncing around, unsecured in a bag.

This cap used with the hydroflask leaks out the top and won't seal shut. So bummed this happened after only 2 months of use. This should stand up to 5x per week usage for a while.

I was needed this!!

I wanted this to replace the screw on cap that came with my hydroflask and it's fantastic! Super durable and has some weight to it.... The lid is insulated too. On the packaging it does specifically state "not leak proof" and if I've got this in the bottom of a bag, not upright, it will leak a little. No biggie though. Only other thing is that the spout is a little hard to open. Overall this makes the water bottle so much more convenient to drink out of!

I have a wide mouth bottle with the straw lid and recently purchased the narrow mouth bottle for my bike. I needed a top that would be easy access while riding and knew i couldn't get the straw for this one. I love this top! it has a small hole to allow airflow since you cant squeeze a metal bottle....i can drink easy while riding and the little loop make its easy to pull the bottle out on the bike.
