Lost my original cap, and this one fits perfectly. It's leakproof and easy to clean. The swivel design is convenient. Great price for a genuine Hydro Flask part.
This cap is identical to the one that came with my bottle. It seals well and doesn't leak. The only reason for 4 stars is that it takes a while to open fully, but that's how all Hydro Flask caps are.
I needed a replacement cap and this one is genuine. It fits my standard mouth bottle perfectly. The material feels durable, and it's easy to drink from. Highly recommend.
I assumed it would fit any standard mouth bottle, but it didn't fit my older Hydro Flask. It fits my newer one fine, so just check compatibility. Otherwise, it's a good cap.
I bought this as a backup and it's exactly the same as the cap that came with my bottle. It’s leakproof and easy to flip open with one hand. Great value.
My old cap was getting worn, so I got this one. It works well, but the plastic feels a bit thinner than the original. Still, it seals properly and fits perfectly.
This cap is completely leakproof. I've thrown my bottle in my bag with water in it, and no spills. It's easy to clean and the swivel mechanism is smooth. Very pleased.
The cap broke after a few weeks of regular use – the hinge snapped. I expected better quality from Hydro Flask. Might have been a defective unit, but I'm disappointed.
