I bought 2 Lid adapter kits from REI about 6 months ago.
Unfortunately I didn't save the cardboard box it came in and there is nothing on the kit that says what it is.
Anyway, it is a 5 or 6 piece adapter kit that fits on different size bottles and it comes with a drinking tube that works in conjunction with the adapted lid.
I have looked all over for this with no luck.
They were only $6 too.
REI doesn't even have the ability to look up what they were.
Anybody know what I am talking about?
