For the Sanremo RoS Thermosuit Castelli has combined two of its most effective pieces of winter kit: the Perfetto RoS Long Sleeve and the Sorpasso RoS Bibtights.

The reasons for this are simple. By combining the two items into one piece, Castelli has eliminated layers around the waist and bibs improving comfort and fit, and the lack of opening at the waist keeps you warm as it prevents cold air from entering.

Just like the Perfetto RoS, the top of the Sanremo Thermosuit is made from a combination of GORE-TEX fabrics. The front provides total protection from the wind and light rain, while the back is stretchy for a comfortable fit and highly breathable.

Reflective taped seams on the shoulders keep water out and improve visibility. A water-resistant YKK® Vislon® zipper provides easy opening and closing, while zippered side openings allow you to easily control ventilation.

The bottom of the Sanremo is made from Nano Flex 3G fabric in the legs for softness, elasticity and warmth, while water resistant panels on the thighs and high front provide protection where you need it most. It is completed with Castelli’s pro-level Progetto X2 seat pad, YKK® Camlock® zippers on the ankle, and reflective panels.

The all-black design speaks of the suit’s completeness but also its core objective: let nothing get in the way of the riding.

Key Features
