The S10's vent layout is designed to channel airflow across the head to help keep you cooler during rides in India's heat and humidity, which is especially useful for daily commutes and longer weekend rides. Riders who sweat heavily may still want to pair it with a moisture-wicking cycling cap for extra comfort underneath.

The S10 is built to be lightweight for extended wear, and like other Sunrimoon helmets, it typically uses a rear dial adjustment system so you can tighten or loosen the fit to suit your head shape and comfort. A secure, well-adjusted fit is important not just for comfort but for the helmet to protect you properly in a fall.

Measure your head circumference just above the eyebrows and match it against Sunrimoon's standard adult size chart to pick between the sizes offered for the S10. If you're between sizes, the rear dial adjustment gives extra room to fine-tune the fit.

The S10 is a general-purpose road cycling helmet rather than a dedicated aero or time-trial design, so it is built to balance comfort, ventilation, and protection for everyday and weekend riding. If aerodynamics is your top priority, Sunrimoon's TT-prefixed models are purpose-built for that.

Wipe the shell down with a soft, damp cloth after dusty or sweaty rides, and remove the interior padding periodically for a gentle hand-wash to prevent odor buildup, which matters in India's humid climate. Let the helmet air-dry completely before storing it away.
