Castelli Mens Tutto Nano Water Resistant Bibtights

Castelli Nano Flex water-repellent fabric is one of those fabrics that seems miraculous. On a dry day it’s as warm and breathable as our normal Thermoflex fabric, but when it rains the water just runs off, thanks to the five-phase nanotechnology treatment.

Features:

• Nano Flex fabric provides outstanding warmth and stretch with water resistance
• Minimal seams for maximum water resistance
• KISS Air seat pad for all-day comfort
• Mesh bib straps for breathability
• Reflective screen-printed Castelli graphic on both legs
