Hydro FlaskStandard Mouth Lids- Accessory for Standard Mouth Water Bottle

I swapped out the standard mouth cap on a standard mouth bottle to this lid and noticed it lined up with no cross-threading or leaks. I used the flexible handle to carry the bottle clipped to a bag during a short hike, and the seal held liquids contained even with bouncing around. Cleaning really didn't require any additional effort as a bit of water and a quick brush were sufficient for any residue inside the cap.

Awesome. Looks fabulous by matching the lip of my wide mouth bottles.

This is exactly how they original lids were designed, then they went to plastic for almost all models.The plastic ones have a thin flat gasket and not an o-ring. It's super hard to get it to come out for cleaning. The plastic ones also are made of two parts that are snapped together in the factory. This is NOT a water-tight seal. So gunk gets inside and is a potential health problem. I drilled a hole in the plastic one and gray goo came out. The entire design of the plastic lids is faulty as cleaning is almost impossible.This, though, is all stainless steel. No seams or ways for water to get inside.It also has a standard o-ring that takes a second to remove and wash. This is also a normal industry-standard size.This is not a knock-off, but made by Hydro Flask/what came on the original model years ago and now is a replacement part. I think they sell one or two models with the stainless steel lid and everything else is plastic.This is a mandatory upgrade that will make your flask last 10-20 years without health issues.

I bought this because my current lid was leaking. A lot. So I'm really happy this one doesn't leak at all! I initially had some trouble putting it on the bottle for some reason, but after a couple of days I've had no issues with that. The straw was easy to trim to the right length, and I haven't had to use the second one yet.

The grandkids need a top that doesn't open completely. We love these and will be buying more. It does sometimes leak but way better than when they knock one of the ones with the screw cap over and the cap isn't on it. They love drinking out of this one.

I really loved this cap. I had a sport cap and the screw cap before I bought this one and I must say it was an upgrade. Of course it comes down to personal preference but in terms of quality it’s a great buy.

Perfect for the gym

Absolutely would recommend! Same as the old ones but hasn’t broken in the last year like my original!
