The Giro Men's Arc Short is your go-to mountain bike short for fun days in the dirt. They are packed with the essentials you need, including a secure zip pocket, exterior waist adjustment, belt loops and hand pockets. The ripstop fabric is lightweight, durable and comfortable, but the best part about this fabric is that it's virtually silent on the bike. Why be distracted by loud fabrics when you just want to hear the sound of your tires connecting to the trail? Not to mention the sounds of you and your friends hooting and hollering down the best sections of trail.
