Customer Reviews Hydro Flask Standard Mouth Flex Straw Cap

Best cap yet!

Stocked up on lids and straws during one of your recent sales; they are great, even colorful, and will make it easier to continually be using all my tumblers and bottles.

I had the sport cap on my narrow mouth bottle originally, which always leaked. I even had the company send me a new lid since they are guaranteed not to leak. Still leaked no matter what I did. When I saw this new straw lid was available, I ordered one for each of my bottles. Doesn't leak! I just wish this lid was available when I bought my bottle so I wouldn't have had this additional expense of replacing the both lids.

Great purchase

Bought this for my wife who is an avid hiker and she absolutely loves it.

Works for what we needed!

Great

Works great.

Love my straw cap! Make drinking from the flask so much easier.

I ordered the wrong top for my flask, and you kind folks replaced it at no cost!! I'll be ordering gifts soon. You know how to treat customers right.

Very convenient. User friendly

we all received branded hydroflasks for work to use with our new water tank system, i needed a straw and this was perfect. Bought one for each of the ladies in the office we all love them.

Very reasonable price and works great.

Perfect! Easy to drink from, easily fits in cup holders slots , great color and keep my water cold!!!! Very sturdy!

Love my hydro flasks.

This cap makes my flask so much easier to use. I hardly ever used it before, but now I use it all the time!

Was looking for a straw lit, and it does the job! I love it.

Wish I had purchased sooner. I love that it pulls apart for proper cleaning.

The directions for cutting the straws for the bottle were way off. Wasted one of the straws, it was 3-4 inches from the bottom. Measure yourself depending on the size bottle you have. Also, don't need to cut straw at 45 degree angle.

Great straw lid! Doesn't leak! The packaging confused me a little and I accidentally cut the straw too short which means I have to fill my water bottle up more often so that's a little bit of a bummer but otherwise it's a good quality lid :).

This revitalized my old 24oz bottle, was debating getting a new one with a wide mouth and straw lid because I didn't like drinking from the standard mouth. Saw that there was actually a straw for the standard size and immediately bought one. I have NOT been disappointed, it's easy to clean forms a great deal and doesn't leak and actually keeps ice in my bottle longer than before! The only gripe I have is that the mouth piece can get a little grody if you're someone like me who always has chapstick on. easy enough to wipe off intermittently though. Love this!

The standard mouth flex straw cap was perfect for my new Hydro Flask. It makes it easy to drink and no spells. Very impressed with that. It actually makes me drink more water throughout the day.

Fits perfectly in my hydro flask bottle. No leaks and it's tightly sealed.

This is a great leakproof cap for use in a car cup holder

When I saw these are an option for the standard mouth water bottles I was ecstatic. It's nice to have choices and using this cap is nice when I want the smaller water bottles for easier transport while running errands or just looking for a lighter carry.
