TRIANGLE 3/4 Motorcycle Helmet for Men & Women - Retro Open Face M

In this review the TRIANGLE 3/4 Motorcycle Helmet is presented as a practical, retro-style open face option for adult riders who want a blend of safety and vintage looks. The biggest reason to buy is its DOT FMVSS-218 compliance combined with an ABS shell and EPS lining that provide genuine impact protection while preserving an old-school Vespa aesthetic. The helmet suits commuters, cruiser riders and scooter users who prioritize comfort, breathability and a built-in sun visor over a full-face sport shell.

Key Features

• DOT-certified safety: Meets DOT FMVSS-218 standards with an ABS outer shell and EPS lining to offer reliable impact protection for street and light off-road use.
• Integrated visor system: Includes a dark tinted dropdown internal visor that blocks 99% of UV for sun protection plus a top snap-on system compatible with many visors.
• Goggle-ready design: A fixed buckle on the rear allows easy attachment of goggles for riders who want extra eye protection or a vintage look.
• Comfortable lining: Soft, breathable interior fabric helps wick moisture and improves comfort on longer rides and in warmer weather.
• Adult sizing range: Available in S through XXL with an adjustable chin strap to secure the helmet and provide a customizable fit.

Who It's For

The helmet is best for adult commuters, scooter and cruiser riders who want a retro open-face style with modern safety credentials and a convenient internal sun visor. It appeals to those who value comfort and ventilation on city and short highway trips and who often ride in sunny conditions.

Riders who require full-face protection for high-speed sport riding or extensive off-road use should look elsewhere, and anyone between sizes should measure head circumference carefully because several users report the sizing runs slightly small.

Pros & Cons
