FAQs

What temperature range are these tights best suited for?

They are designed for cool to cold conditions, typically ranging from 5°C to 12°C (41°F - 54°F).

Do these tights include a seat pad?

Yes, they feature a high-quality integrated cycling chamois designed for long-distance comfort.

Are they completely waterproof?

They are water-repellent, meaning they shed light rain and road spray, but they are not fully waterproof against heavy or prolonged downpours.

How do I ensure the right fit?

Refer to the Castelli sizing chart and measure your waist and hips, keeping in mind that these are designed as a race-fit garment.

Can I use fabric softener when washing?

No, fabric softener will break down the technical fibers and ruin the water-repellent properties of the fabric.

Troubleshooting

Water repellency seems to be fading

Wash the garment with a technical DWR (Durable Water Repellent) refresh product according to the manufacturer instructions to restore the finish.

Fabric feels restrictive during movement

Ensure you are using the correct size; bib tights should be skin-tight but should not prevent a full range of motion. Check that the seams are aligned correctly along the legs.

Setup, Compatibility & Care

To ensure the longevity of your Castelli Free Aero RC Bib Tights, proper maintenance is essential. Always machine wash the garment on a delicate cycle using cold water. Avoid using fabric softeners or heavy detergents, as these can strip the chemical treatment responsible for the Nano Flex 3G water repellency. Hang the tights to dry; do not use a tumble dryer, as extreme heat can damage the elastic fibers and the membrane properties. When wearing, ensure the raw-cut leg bottom is pulled smoothly against the skin to maintain the intended aerodynamic profile.
