The Marker Alpinist 10 and 12 tech bindings without Brakes are essentially the same binding, but the 10 comes with a lower release setting for lighter weight skiers than the 12. The 12 is designed for heavier skiers who need higher release setting. Tipping the scales at just 245 grams, its light enough for long tours but beefy enough to feature lateral and vertical release adjustments to keep you clamped in when you need it most. Two heel riser positions give you added climbing options for when the terrain gets steep. Combine this with high-tech technology and materials, the Marker Alpinist 10 or 12 Without Brakes (Brakes can be sold separately) lets you ski with confidence and security when you are charging on the up and down for earn your turns skiing.
