Review: Perfect Cap for My Hydro Flask - 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.
Review: Great quality, useful new cap - 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.
