The lightest and highest performing splitboard bindings in the world made with incredible attention to detail and no compromises. Womens Arc Pro splitboard bindings have all of the same great features as our standard Womens Arc T1 technology, maximum baseplate cutouts, surfy highbacks, and lower profile ankle straps but are tuned up with premium materials and custom versions. Spark R and D used carbon-reinforced nylon in the highbacks, full Pebax plastics for the straps, ladders and adjusters, 7075 aluminum in the heel loops to make them thinner and lighter, 7 custom made screws and hardware pieces, and lastly, we hollowed out the steel pivot pins to shave a few more grams. Sized specifically for Womens boots, the Womens Arc Pro has shorter and narrower baseplates to fit snug and comfortably, accommodating down to a size 5 US (22 Mondo) boot. Lower and more compact heel loops move the ankle strap mounting point down to hit the sweet spot over your boot while positioning the highbacks lower on the leg for a better calf fit.
