I have a Glacier DuKjug SS bottle and the GSI SS bottle cup(18oz) and they fit together nice. You might try them out unless you're sold on plastic.

The bottle http://www.gsioutdoors.com/products/pdp/1_l_glacier_stainless_dukjug/bottles_jugs/

And here is the cup. http://www.gsioutdoors.com/products/cat/tableware/

I got my 2 from Amazon for 24.00 for the set. (But it was last year)
