Bouchon anti-poussière de sport Klean Kanteen

I got a few of these extra as the kids somehow keep snapping them but they are useful when you are out n about and they leave bottles all over the place!

I've used these dust caps with the Klean Kanteens sports caps for years but like practically all the reviewers mention the plastic snaps from the cap to the loop part so easily.
I was ready to give up using these on my sons bottles but one of them likes having his spout covered up so we've persevered.
Weirdly, fingers crossed, the one he's using has lasted all year yet another time, one has snapped within days.
I think a combination of what parts hit when it's dropped ( and realistically it gonna get dropped ), how much it's dropped and lack of durability of the caps design and materials creates a high possibility your cap won't last long.
I like to keep some spare caps for such eventualities, so as I was doing a klean Kanteen order I added a couple on.
So all I can say is, Good Luck!

Useful for keeping my sports cap clean when my bottle is in my bag. Nice addition to my bottle. A little fiddly to get on but didn’t take took long.

I've had quite a few of these and they always seem to snap when dropped. The ones which came with the bottle lasted so much longer

3 of these have snapped in a short space of time.

My children originally had 12oz KKs that came with these (in different colours) for the sports caps. They are still going strong.

These black ones sold separately seem to be a different plastic which is less flexible.

They probably broke as a result of being dropped or hit on something but that happened with the older coloured ones we have too - in fact more often as the children were younger - but they never broke.
