For years, Giordana has enjoyed having the reputation as one of cycling's premier clothing manufacturers. It earned this reputation, in part, with jerseys like the Lazer a second tier offering that outperforms the top shelf jerseys offered by most other manufacturers. The Lazer's main body fabric is Micro Phase. This is a lightweight, highly breathable fabric with extremely efficient moisture management capabilities. What sets MicroPhase apart, however, is its near compressive level of muscle support. Although it's a lightweight fabric, it provides fatigue reducing muscle support to keep you fresh in the saddle for longer. At the shoulders and collar, the Lazer is made with Asteria 2. 0, which possesses the same supportive properties as MicroPhase. The main difference with Asteria 2. 0, however, is its incredibly tight weave, which is among the tightest in the industry. This makes Asteria not only lightweight and supportive, but incredibly soft, as well.
