Product Description

The Nano Flex warmers are a fixed component for a long while in the Castelli collection, and they’ve finally found a way to improve them. They’ve added an insert on the back in Nano Light fabric to help them bend around your elbow or knee better while keeping all the water protection. More comfort due to more flexibility, and in a slightly more compact package.

Nano Flex
Exclusively engineered by Castelli. They take their thermal fleecy stretch Thermoflex fabric and coat it with millions of tiny nano filaments to create the most water-repellent fabric finish ever. Drops of water stay as spherical balls on top of the fabric or bounce off the fabric without leaving a trace.

Translated from German To the original

Especially at fresh temperatures an indispensable additional equipment. The Legearmer carry themselves very well, do not slip due to rubber, but also do not. The material keeps warm, feels very pleasant and protects effectively against cold. The zipper at the leg closure makes it easy to put on. Top quality!

Gerade bei frischen Temperaturen eine unverzichtbare Zusatzausstattung. Die Legearmer tragen sich sehr gut, verrutschen dank Gummi nicht, schnüren aber auch nicht ein. Das Material hält warm, fühlt sich sehr angenehm an und schützt effektiv vor Kälte. Der Reißverschluss am Beinabschluss erleichtert das Anziehen. Top Qualität!
