# Dimension Nack 143
The Dimension Nack 143 is a pinnacle of Prologo's vision, meticulously crafted for advanced comfort and performance. Designed for both men and women, it prioritizes comfort, performance, lightness, and prevention of perineal area problems.
The saddle's engineered design and size ensure comfort during aggressive riding and on the drops. Weighing only 149g, it combines top-tier performance with lightweight components. The 143mm width distributes weight over a larger surface, enhancing comfort during extended rides. The shortened nose eliminates contact and pressure in the front area, especially when on the drops.
The wide anatomical PAS channel reduces contact and compression of soft tissues and tendons, promoting blood flow. The PAS system, integrated into the base, prevents pressure peaks and numbness in crucial areas. This technology, achieved through unique foam and base design, ensures both performance and durability.
The Dimension saddle features a Nack rail, a monocoque carbon structure with BRC (Braided Carbon Rail) technology, providing exceptional stiffness and lightness.
