if the point isn't to drink ON the bike, then

1) Why insist on locating it in the bottle cage?
2) Why brew it early?

I leave a grinder and brew kit at work, and brew there (either a clever coffee dripper or a Techovorm MochaMaster ... the latter when I'm brewing for the group and not just myself).

We have a winner. thanks.

1. Panniers are generally full
2. Convenience. I make a pot at home for wife and I.

Thanks for the suggestions.

I use a Hydra-Flask, it fits perfect. I think it is 18oz. I can't find the link for it. I have the screw on lid so you need two hands to get a drink but it keeps that coffee hot forever or close to it. I guess it keeps things cold even longer. I may purchase I flip lid for it so I can drink while on the move.

I held one of those in my hands at the store yesterday but couldn't decide if it was a good option with the screw on lid.

When you take the lid off, does the coffee on the lid go everywhere?

That was what held me back. I felt like the lid would get coated in coffee and as soon as you unscrewed it the coffee on the lid would drip everywhere.

Do you experience that or was I WAY overthinking it?

Actually yes. I don't care on the bike but I'm extra careful if I am in the car. I'm using it right now and I'm extra cautious not to drip on anything precious. When I purchased it there was the option for the flip lid but I liked the looks of the hole in the cap that I can carry it with one finger. The flip lid would be better on the bike though in hindsight.

I will second this. I have been using this one for three years and love it. It fits in a bottle cage and doesn't leak. I have used it on motorcycle trips as well, putting it in a bag while it is filled with coffee. No leaks, and it stays hot for hours. I used it yesterday on a car trip. I filled it in addition to the combination french press/travel much I have, and didn't drink it until a little over six hours later, still hot.
