Sugoi apparel has always shown a sophistication and attention to detail that you don't find in most cycling apparel, especially at this price range. Incorporating compressive fabric, an 8 panel design, and open mesh bib straps, the Evolution Pro is Sugoi's best hot weather bib short. Like any decent bib short, Evolution bib shorts are made with stretchy, moisture wicking fabric. What sets them apart, however, is EvoPlus fabric. This proprietary fabric is slightly compressive. That means it supports your muscles to reduce power robbing shock and vibration. The Evolution Pro also features Mobil Mesh bib straps to provide support without inhibiting airflow through the bibs. Evolution bib shorts are made with eight panels for a perfect fit. Flatlock stitching is used throughout the bibs to reduce chafing and irritation. The Evolution also gets Sugoi's RC Pro chamois to manage moisture, reduce pressure on your soft tissues, and move your weight to your sit bones.
