The CS-57 features 28 precision ventilation ports across an almost fully skeletonized top structure, making it one of the most breathable helmets in the Sunrimoon lineup. This level of airflow is a genuine advantage for Indian summers and humid pre-monsoon rides, letting heat escape quickly instead of building up under the shell during long or intense rides.

The FIRMAMENT Light internal skeleton lets Sunrimoon use less traditional EPS and PC material, resulting in a lighter helmet that doesn't sacrifice strength, which matters on longer rides where every gram affects neck fatigue. Combined with its extensive ventilation, the CS-57 is built specifically for riders who push hard in heat and want a helmet that stays comfortable through it.

A 1-second magnetic buckle lets you fasten or release the CS-57 with one hand, even mid-ride. For sizing, measure your head circumference about an inch above the eyebrows and match it to Sunrimoon's size chart, since the helmet needs to sit snug and level for the 3D-GRID and FIRMAMENT structures to protect you as intended.

The CS-57 is available in a clean, minimalist Alpine White, an elegant White Magnolia with gold magnolia accents, and Extravagant Black, all sharing identical ventilation, protection, and comfort features. The differences are purely cosmetic, so pick whichever colourway suits your style without any trade-off in performance.

Remove the interior liner and hand-wash it with mild soap and cool water, letting it fully air-dry before refitting it, since the extensive venting means the liner is exposed to more airflow and sweat than a fully closed helmet. During monsoon season, dry the helmet completely before storage to avoid odour building up inside the skeletonized shell.
