SC Castelli GSM
When the fit indicator points to “Small”, we suggest going one size up.
The Great Summit Mountains are more than climbs—they are milestones that shape character, test resolve, and celebrate achievement. The SC Castelli GSM Jersey is born from this spirit, made for riders who turn every ascent into a personal victory.
Engineered with cutting-edge technical fabrics, it blends aerodynamic precision with outstanding comfort, making it the ideal companion for long, demanding rides. Its breathable structure ensures optimal temperature regulation, while the ergonomic cut adapts naturally to your movement. Three rear pockets plus a zippered pocket provide space for your ride essentials.
Available in two exclusive gradient shades: navy and pink.
