To use this base layer, simply put it on like any other long-sleeve top before your cycling session. It's great for cool weather, so you can wear it during spring, fall, or winter rides. When it comes to pairing, the slim fit allows it to go well with any long sleeve cycling jersey. As for maintenance, follow the care instructions on the label. Usually, it's best to wash it in cold water and let it air dry. This helps keep the merino wool in good condition and maintain its natural properties. Avoid using harsh detergents as they can damage the fabric. Remember, this base layer is designed to dry quickly, so you don't have to wait long for it to be ready for your next ride.
