Using these mountain bike shorts is easy. First, refer to the sizing chart to pick the right size. Then, put them on like regular shorts. Adjust the waist using the 'Set - and - Forget' system to your comfort. You can store small items like keys or energy bars in the zipped hip pockets. When it comes to maintenance, machine - wash them in cold water with mild detergent. Avoid using bleach or fabric softeners. Hang them to dry instead of using a dryer to keep the fabric in good shape. Also, check the seams regularly for any signs of wear and tear. If something seems off, it might be time for a repair or replacement.
