Castelli nano flex 3G sleeves

Castelli nano flex 3G sleeves

Dwarfs in Nano Flex for all conditions
Choose the nano flex sleeves if you are looking for a model that is excellent for dry days, but also that gives you a little extra protection and greater heat in case of rain. We invented the category of thermal fabrics that protect from the water: the Nano Flex owned by Castelli is often imitated, but never reproduced perfectly. No compromise for no condition.

What it is
Nano Flex for the best sleeve: warm and comfortable with dry, water repellent in wet conditions and always hot on the most extreme days.
