MTB PERFORMANCE 3 SUPER AIR MEN. The Elastic Interface MTB Performance 3 Super Air crotch liner combines maximum freedom of movement and protection, thanks to its minimalist design and the additional ultra high-density ischiatic inserts. The concentration of extra padding in the points of greatest pressure provides improved performance even off saddle. Despite being highly protective, this product is extremely lightweight, also due to the perforated foam that boosts breathability. The innovative protective square-shaped insert guarantees perfect saddle stability in the more demanding stages while the central channel provides pressure relief, improving blood flow. 4-density inserts, elasticity, flexibility and reduced thickness come together to provide comfort, even on the most extreme trails.
