Description

It's long gone.

The last time you saw your water bottle's original cap, it was falling down a desert tower. Instead of searching the sands, replace it with Hydro Flask's Wide Mouth Flex Cap. Its stainless steel construction includes Honeycomb insulation to help you drinks stay cold or hot longer. The flexible loop is durable and convenient for hikes and bikes to summer concerts.

  • Water bottle cap fits Hydro Flask Wide Mouth bottles
  • Stainless steel construction with Honeycomb insulation
  • Flexible loop ideal for outdoorsy adventures

Safety Mechanism

  • Familiarity: I've used it once or twice and have initial impressions

Had some leaking issues with the flip cap so bought this as a backup for hiking/touring. Two thumbs up.

Good replacement

  • Familiarity: I've put it through the wringer

This is a great replacement design from the old screw on cap for my 64oz growler.

Does the job!

  • Familiarity: I've put it through the wringer

This does exactly what it is supposed to do, keep your water in your hydroflask and seam sealed to ensure your water/bevy is cold/hot! Easy to use and functional, love the loop to easily carry with you or clip with a carabiner to your pack if there is just no more room. Grabbed an extra just in case!

Lid for WATER!!

  • Familiarity: I've put it through the wringer

My Hydro came with a flip lid and it was great for hot liquids but just wasn't right for water. This lid is perfect if you're using your wide mouth Hydro for water. The handle is super super nice as well.

New design

  • Familiarity: I've put it through the wringer

My first Hydro Flask bottle is almost 5 years old, new cap fits good.

Hi, I have an old-style plastic cap as well. Is the bottom of the cap stainless steel because parts of the plastic of the old cap would flake off after filling the bottle with hot liquids. And is the loop sturdy? I have the large 64oz bottle so it gets really heavy when filled up.

So nice to hold!

  • Familiarity: I've put it through the wringer

Makes carrying a wide mouth so nice to hold or easy to strap on. Love it on my 20 oz for my weekend camping trips! Get one if you don't have it!

I prefer holding onto the loop of the wide a lot over the standard one! Must have for any wide mouth hydro.

Works well

  • Familiarity: I've used it several times

always nice to have some options with hydro flask lids and this one is a nice addition to the collection.

Upgrade time

    I upgraded my hydro flask caps to the new design as the old ones sucked. Much welcomed design change.

    Love me a hydroflask!

      I have Hydroflasks in just about every size but he big boy is my favorite (50 oz.); doubling as both a super-sized hydration device and a weapon should you need something to hit an offender over the head. But really thank you Hydroflask for keepin' all my bevies cold.

      Options

        Nice to have lid options for my hydroflask, since it will last forever. Swap this out for the straw lid when you need the gear loop.

        Reliable

        • Familiarity: I've put it through the wringer

        I was able to speak with the Hydro Flask reps when they came to our office, and she sold me on a few new lids to see how great the improvements had been. She was right! These lids seem much more durable and reliable than the previous lids. As always, I am a very happy Hydro Flask customer :)

        Durable.

          I got an extra one of these for my wide mouth bottles from Hydroflask. It's nice to have an extra around, just in case I misplace one or the other. The insulated design helps keep your beverages cold or hot, and the handle is suuuuuuuuper hardy - though I wouldn't recommend trying to hang an anvil from it to test its durability.

          Great Lid for Cold Beverages

          • Familiarity: I've used it several times

          Bought a wide mouth Hydroflask for coffee, but picked this lid up so I can use it for water as well. Like all other Hydroflask products, this is well designed, made, and ready to be used for years to come.

          Unanswered Question

          Is this stainless on the inside?

          Insulated and Leakproof

          • Familiarity: I've used it several times

          It may seem a little pricey for a lid, but it has an insulation pattern and keeps water cold noticeably longer than the basic flip-up/coffee style lid. Doesn't leak either. That's really all there is to it.

          Solid

          • Familiarity: I've put it through the wringer

          These caps are durable, which is more than I can say for all the other Hydro Flask caps I've broken over the years. I've bought these as replacements for the ones that used to come on the bottle, and so far, so good.
