Light and strong, the Atomic Backland Summit 12 LSH is an all-round touring binding designed for committed skier who crave adventure on every type of terrain. The binding features a Release Value Adjustment that offers release values up to 12 for trustworthy operation, superior safety, and performance. The AutoFlex System utilizes a spring beneath the heel mechanism that automatically provides 5mm of travel between the toe and heel during the arc of a turn. The result is an easy-to-use binding that provides elasticity to support the natural ski flex and further enhance safety, absorption, and performance. The easy Step-in Aid guides the boot perfectly into position for trouble-free alignment. A Climbing Aid adjusts to three stages (0°, 7° or 13°) with a simple flick of ski pole. The Alu/PA Pin Toe and Heel uses a high-performance PA material that’s reinforced with fiberglass to keep the binding lightweight for climbing yet strong and reliable for the down. This brakeless model uses a quick-release leash for safety retention.
