Hydro Flask - Flex Cap for Wide Mouth - Leakproof - Honeycomb Insulated Cap with Flex Strap for Easy Carrying - 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.

High quality, fits perfectly, fast delivery, I am very pleased and happy 🥰🥳 I recommend

Not sure how but we lost the seal on the lid our bottle and thought we would have to purchase a new one at cost of nearly £50, let me check Amazon and there it was, I was able to purchase the lid on its own, great service arrived earlier than expected - thank you

It fits well with my bottle and it's not leaking

This lid for my Hydro Flask is perfect, it stops stuff falling out the flask day in, day out. However, and this is the clever bit, it unscrews effortlessly when you actually want stuff (I recommend hot Vimto) to come out if you're feeling in need a liquid refreshment. How do they do it for the money???

I have more than 5 hydroflasks but this separate lid is the only one making leaks. I wish I could return this. Not even sure if this is an original. I think the original ones have like an inner plastic or silicone inside which this one hasn't. Or maybe they just built the extra lid like this. Still worthless if it leaks.

Unacceptable. I got a used lid. Thanks for exposing me to someone else's saliva

Very tiny and misleading
