I've tried Pearl, Capo, Castelli, even Etxe Ondo. For my build, these are the best fit. I am 6'3", 180 lbs, 43 " chest. The XL fits very well. Rode the black jersey during the hot summer and was just as comfortable as with any of my other non-Giordana jerseys. Quality of material used is a step above most other manufacturers. Have not noticed the zipper problem other reviewers have reported. I am sold on the Laser.
