Care Guide
Washing instructions are printed on a white tag inside each piece of clothing. Following these instructions will help make sure that your gear will last as long as possible. Careful washing and maintenance will ensure the highest performance from your Castelli products and extend their useful life span.
  • Always read the care label before washing a piece of clothing.
  • Close all zips and Velcro fasteners and turn the garment inside out.
  • Hand or machine wash on a lukewarm permanent press cycle (max. 30°C / 86°F)
  • Use a small amount of liquid or powder detergent, not other products that contain fabric softeners, conditioners, stain removers or bleach as they will affect garment performance.
  • Hang dry or dry flat. Do not tumble dry.

Ultralight Summer Cycling Socks For Hot-Weather Rides

Overview

The Castelli A/C 18 Socks are designed for riders who want a light, breathable and comfortable sock for warm-weather cycling, long summer rides and high-intensity training sessions.

Built For Maximum Breathability: The ultralightweight construction helps keep the feet cooler when temperatures rise. This makes the socks suitable for hot conditions where ventilation and moisture control are important.

Durable Nylon Threads: Made with highly breathable and durable nylon threads, the socks balance a light feel with reliable everyday performance. They are built to handle regular riding without feeling heavy.

Ribbed Texture For Support: The ribbed texture adds structure while keeping the sock light and comfortable. It gives a secure feel on the foot without reducing breathability during longer rides.

The Castelli A/C 18 Socks are a practical choice for riders seeking lightweight comfort, durability and airflow in warm riding conditions.
