Using these Castelli bibshort cycling tights is a breeze. Just put them on like regular cycling tights. The stretchy fabric will adjust to your body movements easily. For rainy days, the water - repellent finish will keep you dry, but it's also great for dry weather rides. When it comes to maintenance, machine wash them in cold water with a mild detergent. Avoid using fabric softeners as they can reduce the water - repellent effect. Hang them to dry instead of using a dryer to preserve the fabric's quality. And remember, even though they're durable, don't expose them to sharp objects to prevent tears.
