The Seat Pad

There are many factors that make a great set of bib shorts but the seat pad, or chamois, is the most significant. As the main contact between the body and the shorts the seat pad plays a crucial role in ensuring comfort and support. 

Castelli uses two women’s specific seat pad designs in its road and gravel collections: the Progetto X2 and the Kiss Air 2.

The Progetto X2 seat pad is used in all Castelli’s pro-level shorts. The pad is constructed from two layers. The top layer is seamless and made of a four way stretch microfibre that offers maximum softness and moves with the body to prevent irritation. The layer is seamless to reduce chaffing and has a perforated back that allows airflow. There is a separate saddle shaped cushioning layer that has gel inserts and high-density foam for comfort.

The Kiss Air 2 has a seamless skin care layer to reduce chaffing and abrasion. It is stretchy to move with you. The anatomical shaping of the pad creates the perfect interface between shorts and body. The Kiss Air 2 has variable thicknesses of padding providing the right amount of cushioning in every part of the pad.

Shorts or Bib Shorts?

Bib shorts offer great support when out riding, as the bib straps hold the seat pad and body of the shorts in the perfect place, ensuring great comfort. They are great for when every second counts, and for avoiding any unwanted digging in of the waistband you’re your lent over the drops. However, bibs do involve a bit more hassle as they sit underneath your jersey.

Castelli offers many of its designs as bib-less shorts. These are great if you’re riding every day, training indoors as they are cooler than bibs, or simply don’t want the hassle of straps for any inevitable comfort breaks.

The first thing you’ll notice about the Premio Black Bib Shorts is what’s missing. Castelli has created a new fabric that is woven in one piece to match the various needs of the different parts of your body. In the process the shorts do away with multiple panels and excessive seaming, making a set of cycling shorts that deliver unequalled comfort.

The lower leg has a raw-cut ending with silicone backed yarn to keep the shorts in place, while the four-way stretch fabric in the thigh provides just the right amount of muscle support. The premium fabric extends into the back and is perforated for ventilation. Around the pelvis the fabric is slightly thicker to offer compression.

The cycling shorts use the Progetto X2 seat pad.
