Does replacement standard lid fit?

Was thinking that I'd buy a new lid for my older 24oz standard mouth water bottle but saw a review that said it didn't fit but your CS reply said call. Can you post if it fits or not or do I have to call?

Broken strap!

I love my hydro flask! But one of the sliver disks that hold the strap broke off! Now I need to order a new lid!

It's great but a bit annoying

I love the conveinance of having my drinks staying cold in my hydroflask, but I do have an issue with this particular cap. The cap is great but it makes loud squeaking noises when opening and closing which I assumed was from the wet black rubber ring at the top. I took it out and it stopped squeaking but I left it in because I noticed that when I flipped the bottle water leaked out. Is there anyway to stop the squeaking noises when opening and closing my hydroflask?

It WAS good..

I bought my first hydroflask (21 oz standard mouth) a week ago and I loved this cap, but one of the stainless steel pivots now squeaks when I move the strap and it's only one side, so the other is fine but this one is hard to move the strap on. Maybe just a defect?

Like but need options

I really like this lid/strap for general use - at the gym, park, backyard, beach. Specifically, I like that the handle can be tucked down or lifted up. However, I would like a rigid lid option in addition to this one. When I kayak, I need to be able to clip the lid with a carabiner, and the soft strap would easily shred. I don't want to use the sport cap while kayaking, as it has no cover for the part that goes in the mouth. (who knows what's in the water??? I don't want to see this lid option go away, just a new one added... please! Love Hydro Flask!

LOVE the handle...perfect to carry

Love this top, but it would be even better if it was a flip top with the handle.....waiting because I know it's on the way!

Flex Cap ROCKS!

I have been using the HydroFlask for several years. I never like the complicated tops because they are hard to clean. I do like the standard cap but last year I bought my daughters a new bottle with flex cap
