Ventilation is an essential feature that should be found on any high-performance clothing, and is a key feature in controlling the comfort level while riding or at rest. Vents are strategically placed in the clothing to optimize the use of airflow to transport heat and moisture away. This increases comfort and decreases muscle fatigue allowing you to ride longer, harder and more. On jackets, zipped vents can be located on the back shoulders, under arms, on sleeves, and on the front sides. On bibs/pants, full length side zippers that can be unzipped allowing maximum venting.
