Lost Arrow Pitons

The Black Diamond Lost Arrow Pitons are light enough that you may forget they're on your harness. But when you're in a thin-to-medium crack and need pin-worthy protection, these bad boys get the job done. Black Diamond crafted these out of hot forged steel to keep the weight down (#1 weighs two ounces) and the strength up. Each piton has a number so you can find the correct size during critical moments where you can't shuffle through all your gear.
