TRIANGLE 3/4 Motorcycle Helmet L - Retro Open Face with Visor

In this review of the TRIANGLE 3/4 Motorcycle Helmet (size L) the bottom line is simple: this is a comfortable, DOT-approved retro open face helmet built for riders who want vintage style without sacrificing basic safety. The reviewer found it especially suited to cruiser and scooter riders who value a lightweight ABS shell, breathable interior, and a built-in dark tinted internal sun visor for bright conditions. It is a practical pick for everyday commuting and relaxed weekend rides where full-face coverage is not required.

Key Features

• DOT Certified Shell: The ABS shell and EPS lining meet DOT FMVSS-218 standards to provide crash impact protection for everyday riding.
• Integrated Visor System: A dark tinted dropdown internal visor delivers 99% UV protection and is convenient for switching between sun and shade.
• Goggle Compatibility: A fixed rear buckle and top snap-on parts accept many visors and goggles for flexible styling and added eye protection.
• Comfort Liner: The soft fabric interior offers moisture absorption and breathability for longer rides without feeling clammy.
• Multiple Sizes: Available in adult sizes S through XXL, the size L reviewed here fits well when matched to head circumference and secured with the adjustable chin strap.

Who It's For

The TRIANGLE 3/4 helmet is aimed at scooter and cruiser riders who prefer an open face look and need DOT-compliant protection for city commuting and light touring. Riders who wear a balaclava or thin headliner will find the size L accommodating, and those who value a built-in sun visor will appreciate the convenience.

Riders who need maximum wind noise isolation, full-face impact coverage, or integrated Bluetooth audio should look elsewhere; this helmet prioritizes retro styling, ventilation, and basic safety over full touring features.
