Need a replacement lid for your 12 oz or 21 oz Hydro Flask? We have you covered. The Standard Mouth Loop Cap is a leak-proof, vented cap that allows hot vapors to escape while closing the lid, ensuring a smooth and easy seal.

Perfect for everyday use, as well as the rigors of the outdoors, our caps aide in keeping your Hydro Flask contents hot or cold. The loop allows you to clip to a backpack or messenger bag and ensures your Hydro Flask stays with you wherever your adventure takes you.

The Standard Mouth Loop Cap is now available in new colors, too, as part of the Hydro Splash Line! Hydro Splash colors include Electric Blue, Banana Yellow, Limeade and Perfect Purple.

Std plastic cap fills with liquid if submersed

I have 4 other hydroflasks - all wide mouth. This is the first standard mouth I bought with a different cap. I soaked the bottle and cap in water after buying and now this cap is filled with water that leaks all over the place. So the content IN the bottle are fine but the cap itself has water in it :(

It's just exactly like the stopper that came with my standard mouth hydroflask,

Which is what I wanted: an extra stopper to make it easier to find one when I'm in a hurry and just want to seal my flask so I can get out the door. If you lose your stoppers often you may want to buy an extra or two as well!

Extra hydro-flask caps

Great to have extra caps for your bottles. If one is misplaced can still use your bottles.The bottles are great to take ever where, without the caps one can not keep their fluids hot or cold.

it exactly fits my standard mouth flask. where the original cap went is currently unknown. as long as this one doesn't get that email I'm happy.

With the pour spout

I didn't know if the pour spout would work all that well as they don't really advertise the vents as even being a pour spout, but they do work fairly well to pour coffee.

Works

I'm still amazed when I burn my lips at the end of a day at the mountain. This is a product that I have now purchased for my entire family for Christmas, and they all agree, hydroflask's are the best water bottle that money can buy.
