    Performance Perfected

    After 12 years of evolution and huge kilometres of on the road testing, where exactly have the Castelli design team squeezed out even greater comfort and performance from the already exemplary Women's Free Aero Race Bibshort?

    Well, the heart of any great shorts is the seat pad and for this year the women's specific Progetto X2 Air Donna is more flexible than ever with a new seamless top layer giving you a pad that is virtually unnoticeable and it's possibly the softest pad you'll ever use.

    New GIRO4 leg grippers get enhanced stretch and yet are grippier than previous versions so the pressure is spread wider but without any loss of traction on the thighs. Lastly, the Stripe Mesh straps are lighter in weight, more breathable and yet offer enhanced support, in all honesty, you'll barely notice they're there, but that's the whole point.

    While these improvements are subtle, they all add up to a major step up in comfort, providing support on both the longest and shortest rides.

    Progetto X2 Air Seamless Donna Women's Seat Pad

    The first contact point against the skin is the super-soft upper skin-care material. It's now seamless and even softer than previous generation pads. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it - thicker under the sit bones and thinner on the sides and under the perineum. The results are outstanding comfort with reduced bulk.

    Lastly, to really push home superior comfort levels, perforated viscous padding is added under the highly sensitive ischial and perineum pressure areas, offering luxurious support when you're on the saddle for hours on end.

    Pro Performance

    The Women's Free Aero Race 4 bib shorts are designed with a focus on race performance which has naturally led to a short that is minimalist in its construction, boasts slippery aerodynamics and yet is incredibly comfortable for both long races and tough training sessions.

    Updated seams improve the fit and they now sit on the body even better giving you unrivalled freedom of movement. When it comes to comfort on race day and your longest of training days we think you'll soon discover why these shorts are loved by the Pros.
