0.4-inch Straw Cover Cap for Hydro flask Tumblers | Fit 20-40oz HydroFlask press-in straw lid, 10mm/0.4" Thick silicone toppers, Dustproof seal, Food-grade, Dishwasher safe

I absolutely love these straw covers! They fit my Hydro Flask tumbler perfectly and stay securely in place without constantly falling off. They do exactly what they’re supposed to do by keeping the straw clean, while also adding a fun, stylish touch to my cup. The designs are adorable, and I love that the pack comes with several different options so I can switch them out depending on my mood. They’re made from a soft, flexible silicone that feels durable and is easy to put on and take off without stretching out. They’ve held up really well with daily use. One thing I didn’t expect was how many compliments I’ve gotten on them! They’re a small accessory, but they really personalize my tumbler and make it stand out. The only minor downside—and the reason this isn’t really a “perfect” product—is that my husband isn’t a fan of washing them in the dishwasher because they’re small and can be a little fiddly. That’s more of a convenience issue than a problem with the product itself, and I personally think it’s a small trade-off for how cute and functional they are. Overall, these are a great purchase if you own a Hydro Flask or compatible tumbler. They fit well, look adorable, help keep your straw clean, and are an inexpensive way to add a little personality to your favorite cup. I’d definitely buy them again!

The caps fit my Flask great and it is easy to open & close. I had tipped my flask over at the gym a couple times and water leaked out on the floor - the caps prevent these spills. I recommend.

Great to have

Great item. Love the variety pack.

Nice price for what I got

Love this simple but practical straw cover! I live in the south and we have bugs. So many bugs. It keeps my beverages bug-free and I don't worry about what might come up in my straw! These fit the straw of my 40oz Hydroflask perfectly. Very good quality for the money, they work nicely, and they are so cute too!

It arrived quickly, well made.

Was leery at first, almost all straw toppers fit Stanley, not Hydro Flask, but when they mentioned my brand, I had to try. They fit! Perfectly! Color choices...eh, design choices (as in kawaii)...eh. Aside from the limited color and design choices, I'm am quite happy with my purchase and I would purchase from this seller again. Items arrived safely and quickly. In fact the timing couldn't have been better. My new 32 oz. Hydro Flask all around travel tumbler in bayberry ombre arrived the next day. The toppers fit snuggly, easy to clean, haven't leaked yet...and keeps the bugs out! Had gotten the toppers for a great price during Prime Days, but the regular price is very reasonable for the amount I had gotten. Way to go! Keep up the good work! A+++++

While this doesn’t feel as light weight and as good quality as more expensive tumblers, it is still a good tumbler for daily use as it still holds a lot of water. I also like that it comes with both a plastic and metal straws. The silicone straw cap is definitely too big for the straw but you can still find straw caps which work for this tumbler.
