A Durable, Leak‑Resistant Straw Cap for Wide Mouth Bottles

Swapped my old lid for this Flex Straw Cap and haven’t looked back. It’s compatible with all Hydro Flask wide mouth bottles, has a flex strap that makes carrying easy, and the honeycomb‑insulated, leak‑resistant design has held up tossed in a bag. BPA‑free, toxin‑free, and dishwasher safe for low‑effort cleaning. Just trim the straw length to match your bottle and go.

Almost Perfect

I have one for all my hydro flask bottles. You can't use it without the straw and you have to use the straws it comes with or it will leak, even if it seams like the same size. But other than that it's a great replacement for the usual cap. I know it sounds simple but I love it because I'm always trying to find ways to get myself to drink more water and the flip straw rather than having to unscrew the cap makes a huge difference in my water intake.

Perfect Fit and Quality

I purchased this wide stainless steel cap for my Hydro Flask bottle, and it fits perfectly. The quality is excellent—it’s sturdy, leakproof, and keeps my drinks at the right temperature for hours. I appreciate that it’s dishwasher safe, making cleaning a breeze. The sleek design adds a nice touch to my bottle. Highly recommend this cap for anyone looking to upgrade their bottle’s functionality and style!

Chug cap is great

I've bought a couple of these for different bottles and they're my favorite. I have a 40oz bottle and even when it's full (and heavy), I can leave it hanging by the lid on a hook in my car overnight and it stays attached and sealed. One of them did recently lose the gasket inside, I'm not sure how, but I'd been using it often for over a year and it only happened to one of the lids so I'm guessing that's a fluke. Overall, I'd say great quality and imo the best lid option.

Just buy it

i haven’t put it thru its paces yet but out the box it is solid. it is really well made and not expensive so that’s a win win. i have an off brand flask and it still fit perfectly and seals really well. Plus the straws are able to be cut to size so they can fit any bottle and you have 2 if you mess one up.

No detent to keep the straw in the open position

I have used this lid for a little over a week and it is missing an open detent. When the straw is fully open it works great but if closes just a small bit air is sucked in instead of water. A detent is used to lock the straw closed, but there is no detent that locks the straw open. I'm not sure why that is but it is frustrating when using the lid.
