The Progetto X2 Air Seamless seat pad protects your skin while providing just the right level of padding for maximum comfort, no matter how long your epic ride is.

  1. Skin care layer
    A four-way stretch microfiber top layer offers maximum softness and moves with your body to prevent skin irritation. Seamless construction prevents chafing. Perforated foam backing allows airflow to aid evaporation.

  2. Seamless integrated technology cushioning layer
    A separate component provides no-compromise cushioning, with Castelli’s infinitely variable thickness to bring the right shape to the right part of the body: thicker under the sit bones and thinner on the sides and under the perineum.
  3. Viscous comfort inserts
    Perforated viscous padding is added under the highly sensitive ishial and perineum pressure areas.


A new improved shape, higher-density foam and a softer top fabric make the KISS pad more comfortable than ever.

  1. Seamless Skin Care Layer
    The softest-ever fabric next to your skin for immediate and long-lasting comfort. Seamlessly engineered to reduce chafing and abrasion. Stretchy to move with you.
  2. Dual-Density Infinitely Variable Thickness
    Dual-density infinitely variable thickness gives you the perfect cushioning in every part of the pad. Maximum thickness and density in the ischial zone, tapering to moderate thickness under
    the perineum and minimum thickness at the perimeter.
  3. Anatomical Shape
    Comfort is further enhanced by the creation of a perfect interface to your body during every pedal stroke.


Multi-density KISS TRI-pad foam is optimized for aerobar position on the bike, and practically disappears during the swim and run.
