T Robert T.wrote a review of Castelli Climber's 2.0 Full-Zip Jersey - Short-Sleeve - Men's on July 12, 2015
Familiarity: I've used it once or twice and have initial impressions
By far the best jersey I've worn to reduce the effects of the Texas heat. Downside the price you pay for that is the durablity of the material. Mine showed snags before it was actually worn but I guess that's the price for a lightweight jersey that offers great cooling effect.
