Although backcountry skiing has a lot of pros, there is one major con — no chairlifts. To cut back on the uphill climbs, Zoa Engineering has developed the PL1. The portable rope tow system fits into a backpack to create a lift no matter how remote the location. Skiers and snowboarders trek up the slop one time and secure a rope to snow anchor or tree, then drop the line on the way down. After each pass, users can attach the PL1 to the rope, hit the throttle, and ride back up the mountain, minimizing the time and energy it would take to walk back up yourself. Its rechargeable lithium-ion battery is equipped to handle up to 3,730 feet depending on weight but can be swapped out at any time for extended use.
