The stiffest and most responsive binding in the Karakoram lineup, the Prime Straightlines will give you the support and response needed to not only climb to steep and rugged peaks that you've only dreamed about, but will also take you down in style and confidence so that you can leave your personal canvas on them. Thanks to Karakoram's touring system, you can ascend quickly and efficiently due to the smoothness of the touring bracket, along with dual-height climbing wires and negative lean adjustment on the highback. The Prime splitboard interface includes Active Joining technology which actively pulls the two halves of your splitboard together for a seamless feel, while providing direct power transfer for instant response and fluid transitions from edge to edge. If you demand the most performance from your splitboard bindings, the Prime Straightlines are your weapon of choice.
