handlebar- and bum bag

Hi,

For my planned camping-cum-sightseeing cycle tours, a handlebar bag that
can also be worn as a bum bag (= fanny pack) would be ideal. I googled
for it, but wasn't overwhelmed with what I found so far. Can anyone
recommend one ? My bike has quite narrow drop handlebars with STI
shifters, so the XXL models won't fit.

TIA !
Karen
