FAQs

What temperature range are these shorts designed for?

These shorts are ideal for cool conditions, typically between 8C and 15C.

Can I use these in the rain?

While the fabric is durable, these are not waterproof. They are best suited for dry or misty cool conditions.

Are the straps adjustable?

No, the straps are made from a high-stretch, seamless elastic designed to provide a consistent, snug fit without manual adjustment.

How should I store these between rides?

Store in a cool, dry place out of direct sunlight to prevent the elastic fibers from breaking down.

Is the chamois suitable for multi-hour rides?

Yes, the Progetto X2 Air chamois is designed specifically for long-distance comfort and professional-level performance.

Troubleshooting

Chamois discomfort during long rides

Ensure the chamois is properly positioned before the ride and use a high-quality anti-chafing cream.

Visible wear on thigh fabric

Check your saddle for any rough edges or burrs that could be snagging the technical nylon material.

Setup, Compatibility & Care

To ensure your Castelli Omloop shorts last through many seasons, proper maintenance is essential. Always wash the bibs in cool water (30C maximum) using a gentle, technical-fabric detergent. Avoid fabric softeners, as these can strip the moisture-wicking properties of the Thermoflex fabric. Hang-dry the shorts away from direct sunlight to prevent fiber degradation. For the best fit, ensure the bib straps lie flat against your torso before pulling on your jersey. These shorts are highly compatible with most cycling knee warmers, allowing you to adapt your kit to fluctuating weather conditions.
