About Castelli Pro Seamless 2 Arm Warmer
Wide temperature range combined with high-stretch seamless comfort makes this Castelli's most versatile warmer.

With Castelli's pro riders they set out to make a better seamless arm warmer. Others on the market are made with a nylon/Lycra® blend that tends to hold moisture, but they knew they could get better moisture management with a polyester yarn. Working with polyester makes it more difficult to get the right stretch, return and manufacturing consistency, though. It took a year longer than they thought, but they're all glad they stuck with it. These warmers are a pro rider favourite 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.

About Castelli
Castelli are an Italian clothing manufacturer based in Fonzaso, Italy. In 1876 Vittore Gianni opened a clothing shop in Milan where he created clothing for AC Milan, Juventus, the Milan Ballet and cyclist Alfredo Binda. In 1935 Armando Castelli joined the business and four years later bought the company. He kept these high profile clients and continued making cycling clothing for riders including Fausto Coppi. In 1974 the scorpion logo was created and Castelli was born. Since then they've been at the forefront of innovation creating the first lycra shorts, coloured shorts and use of sublimation.
