New this season is the Ion 10 which is the same as the Ion 12 but with a lower release value (4-10). Now you can pick the Ion that fits your skiing type best. Its one of the best, if not THE best, ski touring bindings on the market. It is a powerful and lightweight freeride touring binding which is very easy to use. Game changing forward pressure, wide mount and refined toe jaw dynamics plus unique step-in and brake features yield superior freeride performance in the lightest setup you can ask for. It weighs only 585 g / 1 lb 4.6 oz per binding! The IONs efficiency, power transfer and sleek design is beyond any binding in its category. Power up, then charge the descent.
