Klean Kanteen Sports Cap 3.0 Black

I'm going to go against the grain here: good design, works well but I prefer the older style. I find this one harder to open than the previous design of strictly hard plastic. Not great for younger kids (hard for them to open) but perfect for adults. Maybe with use it will become less stiff and easier for my 3 year old to open independently.

Great sport cap lid. These ones replaced the old version our bottles came with and it's a better design. More rubber than the hard plastic.

Perfect for my kids when they're at school or playing sports. Only downside is they've pushed the plastic nib inside a couple times and it will leak.

While it is a perfect update on the sport cap 2.0 in terms of drink flow and noise, it does leak substantially whenever the plastic nib is pressed or the bottle is upsidedown.

Really handy to have the option to change lids.
