I am driving in a travel suit from Touratech as well. I choose the Companero Worldwide Black. So far and after testing it 2500km in the Alps and Dolomites during sunny and rainy days I am happy with my choice. In addition I will by a light rain coat (not overal), since the all weather add in the warm rain (yes it exists) is to hot. 50 EUR ones will do the job (jacket and trouser)
The helmet is a Schuberth C3 Pro. Lets see if I spend the money on a audio system later. The helmet is great though, the visor could be stronger to keep position semi open.
For water and dust tight travelbags my choice was for Ortlieb Bags (the Big Zip with 140l and a MotoRack with 90l). Pictures will follow soon after my arrival and first gear up ‘n go.
