To use these 45NRTH Naughtvind cycling pants, simply put them on over your regular cycling clothes or bibs. Make sure to adjust the waist and ankle to fit you comfortably. When you start to feel too hot during your ride, you can open the ventilation areas to let out the excess heat. For safety, the reflective accents will help others see you in low-light conditions. As for maintenance, it's best to follow the care instructions on the label. Usually, you can machine wash them on a gentle cycle with cold water and mild detergent. Hang them to dry to keep the shape and material in good condition. Avoid using harsh chemicals or bleach as they can damage the wind- and water-resistant properties of the pants.
