The race/roadie-look silky fabric of the SS Pro immediately makes it stand out. It wicks and dries OK, and the slippery feel means easy movement. The sleeves are unelasticated but not baggy, and though the hem is elasticated, overall fit is still relaxed. Shoulders are seamless.
You only get a relatively short and rattly neck zip, which limits ventilation, but there's room for loads of stuff in the three wide rear pockets. Just watch the broad tops don't let stuff fall out. The fabric durability is good, with just fluffing rather than pulled threads or pinholes the result of snagging or chafing, but the price is high for the simple design unless you love the logo.
A good riding top, but pricey unless you really want that Adidas name...
