Rick Steigerwrote a review of Castelli Climber's 2.0 Full-Zip Jersey - Short-Sleeve - Men's on September 3, 2015
Familiarity: I've used it several times
Simply the best hot weather jersey I've ever worn, air flow is amazing. Fabric is extremely light, almost hollow and very comfortable feel. Size up one size, I'm 6 foot 181 pounds do some weight lifting and needed a XXL.
