Kneelwrote a review of Castelli Wind Baselayer Short Sleeve Top on September 19, 2013
Familiarity: I've put it through the wringer
I have both the short sleeve and long sleeve version and really like them both. As a layer - they help block the wind and you don't get too hot if you wear the right one. Short sleeve is good for cooler temps in the fall and long sleeve is better when it's colder.
