FAQs
What makes the Progetto X2 Air Seamless seat pad special?
The Progetto X2 Air Seamless pad uses variable thickness padding, perforations for breathability, and a soft, seamless top layer to reduce friction and improve air circulation, providing targeted comfort and dryness.
Are these shorts suitable for very hot weather?
Yes, the Endurance Evolution fabric offers excellent moisture management and the Progetto X2 Air Seamless pad is designed for maximum ventilation, making them well-suited for hot conditions.
How do I determine the right size?
Consult the Castelli sizing chart for the most accurate fit. Since fit is personal, consider your waist, inseam, and general body shape. Reading reviews from other cyclists can also provide insights.
Can I wear underwear with these bib shorts?
No, bib shorts are designed to be worn directly against the skin without underwear. Underwear can create friction and bunch up, negating the benefits of the seamless chamois pad.
What is the main difference between these and racing bib shorts?
The Endurance 4 shorts prioritize sustained comfort and support for longer durations, often using slightly more forgiving fabrics. Racing shorts typically focus on maximum compression and aerodynamic fit for shorter, high-intensity efforts.
How long will these shorts typically last?
With proper care, including correct washing and avoiding tumble drying, these shorts can last for multiple seasons of regular use, maintaining their comfort and supportive qualities.
Are the GIRO3 leg grippers tight?
The GIRO3 leg grippers are designed to be secure without being constrictive. They use a soft elasticated material to hold the shorts in place comfortably, preventing them from riding up.
Troubleshooting
Bib straps feel too tight or too loose
Adjust the position of the straps on your shoulders. The mesh design allows for some flexibility; ensure they are snug but not constricting.
Chafing around the leg openings
Ensure the GIRO3 leg grippers are lying flat against the skin. If irritation persists, check the sizing or consider a thin layer of chamois cream under the grippers.
Seat pad feels uncomfortable after a few hours
Verify the shorts are the correct size and the pad is positioned correctly. Some break-in time may be needed. Ensure you are wearing appropriate cycling underwear (or none, as designed) and have adequate saddle height and tilt.
Fabric losing elasticity or support
Review washing and drying instructions. Avoid high heat and harsh detergents, which can degrade the fabric over time. Ensure shorts are not overstretched when putting them on.

Setup, Compatibility & Care
Setup:
These are bib shorts, meaning they integrate straps for a secure fit. There is no specific setup required beyond wearing them as intended. Ensure the bib straps are comfortable and not overly tight or loose.
Compatibility:
The Castelli Endurance 4 Bib Shorts are designed to be worn with standard cycling chamois cream if desired, and are compatible with all types of cycling jerseys. They are suitable for use with road bikes, gravel bikes, and mountain bikes.
Care Instructions:
To maintain the performance and longevity of your bib shorts, follow these care instructions:
- Washing: Machine wash cold (30°C) on a gentle cycle with mild detergent. Avoid washing with abrasive materials like zippers or Velcro.
- Detergent: Use a small amount of liquid detergent. Do not use fabric softeners, bleach, or harsh chemicals, as these can degrade the fabric and chamois.
- Drying: Hang dry only. Do not tumble dry, as high heat can damage the materials and elasticity.
- Storage: Store in a cool, dry place away from direct sunlight.
