The TT-23 comes with an integrated visor-style lens that shields your eyes from sun glare, wind, and road dust, so you don't need separate riding glasses for most daytime commutes. It's a useful feature for Indian riders dealing with intense midday sun, letting you keep visibility clear without squinting through traffic. The lens can be flipped up or removed when you're riding in shade, at dusk, or indoors.

The TT-23's shell and integrated lens are shaped to sit close to the head and reduce wind drag and buffeting, borrowing design cues from Sunrimoon's TT time-trial lineup rather than a bulkier, vent-heavy commuter shape. This makes it feel quieter and more stable at speed on open roads, while still remaining practical for everyday city riding.

While the TT-23 prioritises its streamlined shell and visor over a large vent count, the IONIC+ antibacterial liner is designed to manage sweat and moisture during warm, humid rides, keeping the interior fresher for longer. Riders doing longer or more intense rides in peak Indian summer heat may prefer a heavily vented model like the CS-57, but the TT-23 is well suited to typical commuting conditions.

Measure your head circumference about an inch above your eyebrows and check it against Sunrimoon's size chart before ordering, since the lens and retention system are designed to work together only with a snug, level fit. The helmet should sit firmly with the visor aligned just above eye level, without pressure points at the temples.

The TT-23 uses a 1-second magnetic buckle that opens and closes with one hand, making it easy to put on and take off quickly at traffic stops or when locking up your bike. Combined with the lightweight shell, it's built to feel unobtrusive during long commutes rather than adding bulk or fatigue.

Remove and hand-wash the liner with mild soap and cool water, letting it air-dry fully away from direct sunlight before reinserting it. Wipe the lens with a soft, dry microfiber cloth to avoid scratches, and during India's monsoon, make sure both the lens and liner are completely dry before storage to prevent fogging, odour, or mould.
