Dallin Tolmanwrote a review of Castelli RS Superleggera Jersey - Men's on April 20, 2017
Familiarity: I've put it through the wringer
Fit: Runs small
Most comfortable Jersey. The sleeves are paper thin and the material is super soft and doesn't cause any irritation. Fits small so order a size up. I usually go with a Medium and fit into the Large.
