Water bottle that won't leak in lunchbox?

Any recommendations? I have yet to find something that doesn't leak when left on its side. Thanks!

Funtainers don't leak.

Our Contigos are great. They are kind of like Funtainers. I love our LLBean Klean Kanteens too but they are not as reliable for no leaks, if DS puts on the cap without pushing the spout all the way back down it will leak if it's on its side.

Contigo!!! Before we had kleen kanteen and camelback...both leaked horribly.

The litterless juice boxes work well. I also like the vapur bottles with a screw top lid. The vapurs can be frozen so they also double as an ice pack. I did buy the screw top lids seperately from amazon as the bottles comes with sports tops that my kids aren't good with closing.

We used Funtainers before but now we use Camelbaks for the past 7-8 months. No leaks with either.

we love this Thermos bottle because it doesn't leak and it keeps the drink COLD!
