The fabric of the Contour Plus is treated with titanium oxide, which is designed to fragment the moisture molecules for quicker evaporation.
We can't test the physical chemistry or investigate things at a molecular level, but the fabric certainly does a good job of moving sweat and staying dry on those hot days. We're a bit out of odds with the fit though.
This could be down to the differences between Anglo and Italian bodies but the arms felt tight and aren't really in line with the front of the jersey, which is quite baggy. However, features such as the full-length zip are a bonus on hot days, as are the antibacterial under-arm panels. Quality is high, with flatlock stitching throughout, a silicon hem gripper and the standard array of rear pockets. It's just a real shame it didn't fit so well.
