Hydro Flask 16 oz. Wide Mouth with Flex Sip Lid - Review 2023

Best for your ice-cold beverages

Hydro Flask 16 oz. Wide Mouth with Flex Sip Lid can go head-on with your demands. Whether it’s carrying a hot drink to your winter escapade in the mountains or a cold drink to refresh you while roaming around downtown.

It’s also available in a wide range of colors like cobalt, black, white, and popping clementine. You can choose one that suits your preferences.

This Hydro Flask tumbler comes with TempShield technology. Its double-wall vacuum insulation helps maintain your beverage’s temperature longer. This feature is present in Hydro Flask 24 oz. Standard Mouth as well. It also keeps the water bottle condensation-free on the outside.

One of the things we like about the Hydroflask is its wide-mouth opening. Spanning 2.9 inches means you don’t need a funnel when transferring beverages and standard ice cubes easily go in. And we love that, amazingly, ice cubes stay solid for 2 days when it remains closed.

It is a great part of your gear if you are exploring Sedona or other desert destinations. But you’ll have to drink up that coffee or tea. While the product description promises to keep hot drinks hot for as long as 6 hours, our testing and reviews have shown hot drinks only stay piping hot for closer to 3 hours. Our favorite bottle for hot drinks is the Yeti Rambler.

Another vital thing to remember when looking for a water bottle: Is it chemical-free? Rest assured that Hydro Flask 16 oz. Wide Mouth with Flex Slip Lid is both BPA and Phthalate-free.

Now, this Hydro Flask tumbler has a Flex Sip lid. It’s a no-fuss, twist-and-drink mechanism.

But this perk comes with a downside.  The lip area is open to the elements and could be exposed to dirt and dust, particularly within the wilderness or polluted city centers. If you want to have a covered mouthpiece in your water bottle, you might want to check-out CONTIGO Autoseal Water Bottle and Takeya 24 oz. Originals Insulated Water Bottle.

The sip lid is also designed particularly for your coffee and tea. It may not be the best fit for your ice-cold beverages as well.

All Hydro Flask water bottles are easy to hold since they’re powder-coated (scratch-resistant). The Flex Strap has a flexible material for a comfortable 3-finger grip. You can also clip it to your backpack without any hassle or let it sit in your car’s cup holder while you focus on the road.

Overall, Hydro Flask 16 oz. Wide Mouth with Flex Sip Lid ticks the basics. But some of its features don’t live up to its promises.

What is it good for?

This tumbler model from Hydro Flask is ideal if you’re someone who carries coffee to work and only needs it within the first three hours. But for late afternoon caffeine lovers who expect to bring their favorite coffee from home, the Hydro Flask 16 oz. Wide Mouth with Flex Sip Lid will be a no-go. You can check out the Klean Kanteen Insulated Classic 20 oz. Water Bottle. It keeps your favorite coffee hot all day long.

Beachcombing in Miami or wandering the squares of Savannah? Carry your favorite ice-cold drink on a Hydro Flask tumbler. Since its opening is 2.9 inches wide, you can drop some ice cubes in. Rest assured that they won’t melt for hours and hours.

Is it the best of the rest?

With pro-grade 18/8 stainless steel build, the Hydro Flask 16 oz. Wide Mouth with Flex Sip Lid assures no flavor-retention. It’s the most common material for reusable water bottles.

The straight-up no BS twist to open/close lid of this Hydro Flask tumbler with the Flex Sip lid makes it hassle-free to quench your thirst. But keep in mind to twist it with slight wrist force only. Turning it too hard counterclockwise can open the entire water bottle. Doing so might also spill your drink or untwist the whole top part of the Flex Sip lid. Perhaps, change to Hydro Flask Wide Mouth Straw Lid to avoid this dilemma.

If you’re more of a flip-the-lid person, you’ll also like Takeya 24 oz. Originals Insulated Water Bottle and CONTIGO Autoseal Water Bottle.

You won’t have any troubles carrying your Hydro Flask 16 oz. Wide Mouth with Flex Sip Lid. Its Flex Strap hugs your fingers, unlike the solid plastic handle you’ll see in YETI Rambler Water Bottle.

When it comes to cleaning up, it might get a little tricky. Confusing at first, but you’ll get used to it after some time. After taking off the lid from the bottle, you can dismantle it by turning the top and bottom section counterclockwise.

Once the top cover is off, remove the silicone inside. This way, you assure that every corner of the lid is squeaky clean. Otherwise, you risk mold formations inside, and that’s in no way good.

You end up with four parts that you now have to assemble after drying. And that’s a lot for a water bottle. Lay the silicone, twist the top cover clockwise and do the same for the bottom section.

If you’re already annoyed at how demanding that is, take a peek at Hydro Flask 24 oz. Standard Mouth for an easy cleaning process.

Hydro Flask 16 oz. Wide Mouth with Flex Sip Lip is one of the most loved water bottles out there. It might not tick off all your requirements. Because really, no product is “perfect.” And if you know one, we would like to hear about it.

Conclusion

For roughly $35, this Hydro Flask tumbler is one of the pricier options among some of its competitors.

It gives you the option to sip your coffee for ease of drinking coffee on the go. It is ideal for any eco-warrior who wants to reduce waste. Besides, this Hydro Flask tumbler is compatible with most brewing machines.

Quality-wise, it comes with a professional build, and it’ll get the job done. But it doesn’t offer the best value for your hard-earned money. Some water bottles in the market give you better insulation. Or 100% leak-proof without the need to switch to another lid. And they are a few bucks cheaper as well!

Although specially made for coffee, ironically, it can keep cold beverages cold for longer.

But if you have a collection of Hydro Flask tumblers, you might want to try out this one and see for yourself. Chances are, you already have a Hydro Flask Wide Mouth Straw lid to interchange with the Sip Lid. But if you don’t, it means some more bucks flying out of your wallet.
