## Questions & Answers

**Q: Does it leak?**
A: No it has been 100% leak proof! Mine worked great for a while on my hydroflask. Then the lid broke in half and I can't get the broken part off my water bottle making my hydroflask unusable. Now I have to purchase new bottle... not super happy about that.

**Q: Does it fit a hydroflask 25 oz wine bottle?**
A: I just happened to have the wine hydro flask. I never thought to try. I immediately pulled it out tried it. It dies fit. Thank you for asking so now I know I can sip 25 oz of wine to my hearts content. :)

**Q: Does anyone have a hard time sipping? I feel like the air vent doesn't work in the lid**
A: Yes, they messed up on this design.  There is a little vent behind the spout.  The first version allowed air to pass through.  This new version is completely sealed.  If u puncture it, you will sip fine, but it can leak if tipped over.  The people who say to loosen the cap are just making air to pass through the lid.  If they flip the bottle upside down, it will leak from the lid

**Q: Will this fit a 25 oz s'well bottle?**
A: No, it will not fit a swell bottle

### ⭐⭐⭐⭐⭐ Exactly what I needed

### ⭐⭐⭐⭐⭐ Fits great on the 21oz hydro flask (standard mouth)
*by G***G on October 18, 2019*

I've been using my hydro flask bottle for several months and has been great. However, the regular cap that comes with the bottle makes a lot of noise when opening and closing. It is also a bit tough to drink out of when walking or doing anything active (it'll just spill everywhere). I was looking at the hydro flask sport cap and was turned off by the bad reviews of it leaking. I saw this "The Coldest Water" straw cap as a "frequently purchased" product and saw the good reviews. Decided to give it a try. As usual, amazon shipping is great and received it in 2 days. I received instructions from the seller on how to cut and insert the straw a day before so I had an idea what to expect. When I received it, i gave it a quick wash (please wash it because the rubber tip has a slight manufacture scent to it, which I expected). I cut the straw to size at an angle. The straw is soft enough to cut but hard enough to last. The package also came with 2 straws as well as a straw cleaner. I inserted the straw into the rubber straw holder on the cap and screw it on my bottle. Immediately, I tried the leak test by turning it upside down, shaking it, etc. No leaks. I've been using it for 2 days now and have not leaked on me. One major "bad" thing I noticed is the tip is a little tight to rotate out to start drinking. There is a little plastic platform where you can use your finger to push down but takes a bit of finesse. I wish there was a mechanism that would allow easier rotation as well as prevent touching the tip with your fingers. Some smaller things I found is there is a loud "suction" sound when you finish your sip but I assume this would be the case for any "suction/straw" caps. Also I noticed I need to suck a little harder when the bottle is full. I wouldn't remove 1-star from the cap from these "issues" though. Still a great cap so far.
