A better arm warmer.

Working with professional cycling team, Team Ineos, Castelli worked to develop a better seamless kit to take us into the next riding season and we are happy to welcome the Castelli Pro Seamless Arm Warmer. Other arm warmers on the market are made with a nylon/Lycra® blend that tends to hold moisture, but the development teams at Castelli knew better moisture management could be achieved with polyester yarn. Working with polyester makes it more difficult to get the right stretch, return and manufacturing consistency, though.

Although it took Castelli a year longer than they thought, the final product was well worth the wait. These warmers are a pro rider favorite because they're crazy light and they're extremely warm for their weight, yet even in milder conditions, you don't overheat. They're so stretchy you hardly feel them on, yet when you take them off they occupy a fraction of the space that normal warmers would take in your pocket.

Features:

  • Mid-weight seamless arm warmer
  • Surprisingly warm without causing overheating
  • Unique polyester/nylon/Lycra® 78%/15%7% blend
  • Fully seamless construction
  • Folds up extra small
