If you're the type who sleeps in rando boots and chows down on carbon fiber for breakfast, the Arva Carbon 2. 00 Probe is the stuff your dreams are made of (carbon, obviously). Weighing in at an astonishing 3. 5oz, the Carbon 2. 00 is the lightest probe Arva makes, and the official probe of the epic Patrouille des Glaciers ski mountaineering race, a 53-kilometer Swiss monster that pushes gear and athletes to the limit. With a tension-locking Kevlar cord and markings every 5cm, the Carbon 2. 00 is the choice if you were born light 'n' fast, whether you're competing or just getting pre-work turns on the regular.
