To use this men's cycling jersey, simply put it on like you would any regular shirt. The full - length YKK zipper makes it easy to adjust the ventilation according to your comfort. Use the three back pockets to store small items like your phone, energy bars, or keys during your ride. When it comes to care, machine wash the jersey in cold water with like colors. Avoid using bleach or fabric softeners as they can damage the fabric and the 37.5 technology. Hang it to dry to maintain its shape. Don't iron directly on the fabric, as high heat can also affect the performance of the materials. With proper care, this jersey will serve you well on many cycling adventures.
