The Nitro Vertical ST is a splitboard binding for intermediate to expert riders who want a light, responsive setup for long tours, technical backcountry terrain, and demanding descents. It is built on the Spark R&D Tesla T1 base, a simple, lightweight interface that switches quickly between touring and riding modes and keeps working in cold or icy conditions. An upgraded EVA pad adds cushioning and shock absorption underfoot without dulling control. Nitro rates the Vertical ST at 8 out of 10 for response and 7 out of 10 for comfort.
