Fuel bottle holder?
 

I did a search and didn't find anything. I keep seeing bottle cages with a plastic part to hold the top of the bottle and was wondering who makes them and where to get one. If there are better ways of carrying a fuel bottle then that would be good info as well.

I use these for my Sigg water bottles

works pretty good, a little flexy, but the two I have seem to be holing up ok fo rthe last 6 months or so. Mine usually holds a sigg full of hot tea on my way to work, and the occasional fire road.

I got one at Wal-Mart for $3 that is adjustable to fit different size bottles and have used that this past summer for my 1 liter fuel bottle. The addition of a bungee around it keeps the jug secure.
