Flex Straw Cap for Wide Mouth - Leakproof - Honeycomb Insulated Cap with Flex Strap for Easy Carrying - Dishwasher Safe - Black

I really like this Flex Cap. It fits my wide mouth Hydro Flask perfectly and feels super sturdy. I’ve carried it in my backpack and car cup holder, and not a single leak so far. It’s also really easy to clean, which I appreciate since I use my bottle every day. The stainless steel looks great and has that high-quality feel Hydro Flask is known for. If you need a solid replacement or just want a backup lid, this one’s worth it. Simple, durable, and completely leakproof.

I've been thinking of getting one of these caps for a while, and I'm glad I finally did. It's really encouraged me to drink more water now I don't have to undo and redo the cap every time. It sounds like a small issue but it makes a difference. The build quality is great as you would expect, absolutely no leaking. The size is a little larger than the basic cap height-wise, but there is no noticeable weight difference. Easy to clean as it comes apart easily. No metal parts so no need to worry about rust. I'd recommend for any Hydro Flask users who like to use straws.

This lid / cap was a perfect replacement for one that got damaged ( affter 2yrs of constant use) - it has saved the much loved , sticker covered bottle for ongoing use! Well pleased!

PRICE At £14 this lid is expensive - I’ve bought decent water bottles for that price; however, my partner and I had already committed to buying the Hydroflask ~1L and were so impressed by it that I even went and bought a 1.9L bottle too. I got two of these lids, with the intention of swapping mine as and when depending on the bottle I’m using, and am fairly impressed. EASE OF USE These lids are definitely easier to use on the smaller wide mouth bottles as you are taking the whole weight of the bottle mainly on your wrist when you drink from it. I work in a bar so am used to flipping large bottles over with my wrist alone and still occasionally need to use two hands to support my 1.9L. That being said it is doable and becomes comfortable after time. LEAK PROOFING When we first received these lids, I got drenched every time I tried to take a drink and my partner could not get any water to come out of hers. I’ve kind of figured out the best way to fit the lid but with no real instruction on the packaging it was very trial and error. It would seem that if you screw the lid on too tight nothing will come out and obviously if you don’t screw it on tight enough it will leak. Also when drinking be careful not to tip the bottle too far or it will leak from the air inlet hole. That being said when the lid is in the closed position nothing’s getting out of it so I can carry it around in my bag with my laptop etc without any worries. CLEANING The lid has a rubber gasket on the inside and breaks down into three parts. This makes it very easy and convenient to clean.

fits a wide mouth hydro flask and is leakproof. Great quality. Use it with cold or hot drinks and is easy to clean

I love this lid. It not only serves its function but you can take it apart and clean it thoroughly and then reassemble it with ease. The handle is fantastic and I find myself carrying it around like a handbag it its not carabinered to my bag . I've had this lid for around 2 years now and it hasn't broken or worn. Would definitely recommend!

Comes with two straws. You need to flick the lid all the way back to drink and isn’t adjustable.

Very good. But cup needed
