Congrats, you have a Hydro Flask (or are thinking about getting one soon)!  It's hard enough deciding which Hydro Flask bottle to get, but have you also thought about which lid you'll use?

Hydro Flask has four (4) lids available right now on Amazon: Flex Cap, Flex Sip, Flex Straw, and Straw Lid.

In this video, we go over how each one works, what we like and don't like about each design, and how we use them.

If you'd rather read through the review than watch the video, see the written summary below.

​Hydro Flask has four lid options, and you might be asking which lid is best for you. We've reviewed and tested each lid extensively, and here's what we think.  Links are in the description.

Which one is best for you?  Well, it depends on how you want to use it, but we can tell you how we like to use them.

• We like using a Flex Cap with a SplashPro in our largest bottles when we're doing something active. We find it easier to get smooth pours and bigger gulps of water while also keeping water out of your face.
• For sipping at work or in the car, we like using Flex Straw with a FlavorFuze Straw infuser to add some flavor.
• And for coffee and tea in the morning, we prefer to use the Flex Sip lid with a smaller Hydro Flask like a 16oz.
• The only lid we recommend against using is the original straw lid. If you want a straw lid, just get the Flex Straw.

​Also works with a ​FlavorFuze Straw Infuser

Many people search Google for things like:

• How to make loose leaf tea in a Hydro Flask?
• Can you make hot tea in a Hydro Flask?
• Tea infuser for Hydro Flask
• Tea strainer for Hydro Flask
• Tea steeper for Hydro Flask
• Making tea in Hydro Flask
• Hot tea in Hydro Flask
• Loose leaf tea Hydro Flask
• Brewing tea in a Hydro Flask

We get a lot of questions about this too.  Hydro Flasks are primarily used for water, but plenty of people would love it if they could have different flavors, like fruit infused water, coffee, or tea.  In particular, tea is what we're focusing on today.

And unlike some concerns with plastic and even aluminum, from what we have found, stainless steel won't leach chemicals or pollutants into your beverage.  Flaske has a great article covering more details about the question of "Are Stainless Steel Water Bottles Safe to Drink From."  So does Elemental Bottles, where they recommend looking for bottles that are either made from #304 or 18/8 stainless steel (Hydro Flasks are made from 18/8).  We highly recommend checking these articles out if you have any other questions or concerns.

You should also consider what type of Hydro Flask you want to use, since that can have an effect on which type of tea infuser will work best.

Now that we know putting hot tea in stainless steel bottles like Hydro Flasks is safe, let's look at the best ways to do it!
