You see,
it depends on what you mean by vintage. I was around back then, and I don't ever remember seeing a wool trainer like that Molteni in real life. I saw lots of sweaters, and a couple of wool bike jerseys. So are you looking for the 'retro' look of Rivendell. the classic racer look epitomised by the Molteni, or something else again entirely? Btw, check out smartwool, they have a nice website, and some of the nicest wool garments you will ever see.
