We have had Camelbak & Polar ones. My wife likes them. I really don't care, they don't do that much.

There aren't that many days I actually care about this. If I do though, I would rather take one of my Kleen Kanteen ones.

I have several Kleen Kanteen insulated SS bottles that fit just fine in the bike water bottle holder. The 20 & 25oz Classic will fit. the 16 & 20oz "TKWide" fit.

With the classic you can literally use the "Classic Sport Cap" and it pretty much just turned it into a bike water bottle. They actually work fine on the bike, you just don't squeeze the bottle since it's metal. The newer bottles don't really have an appropriate cap so you would need to pull over to drink. The "Chug Cap" might work on the bike without pulling over but I've never tried it.

I very very rarely have actually used them just for going for a ride but I know they work cause I have used the Kleen Kanteen bottles to take coffee/tea with me on my bike for commuting.
