Not sure if mentioned however, i went through Croatia & Italy for 7 days with a Wildcat Tiger (w/ dry bag). Worked nicely, not as expensive as other systems and didn't swing around too much. Managed to get a decent amount of stuff in there too - 3 jerseys, spare bib shorts, hoodie, jeans and underwear. Could have done with more room as I had a load of stuff in jersey pockets but this would only be for luxuries to be honest.
