TRIANGLE Convertible Motorcycle Helmet — DOT-Certified Modular Full-Face with Sun Visor

The TRIANGLE Convertible Full-Face Motorcycle Helmet is a DOT-certified modular helmet that converts quickly between a fully enclosed full-face and an open 3/4 design for versatile, all-weather riding.

This helmet combines certified crash protection with practical features designed for everyday riders: a tough ABS shell with multi-density EPS lining, a removable front mask for two riding modes, a clear exterior shield plus an internal sun visor, and a ventilated, washable interior. It’s built to fit adult heads in sizes S through XXL and includes a protective storage bag to keep the finish pristine when not in use.

How does the TRIANGLE modular design help when conditions change?

You can switch between full-face and open-face configurations without tools, giving you immediate flexibility when the weather, traffic, or visibility shifts. Removing the front mask reduces wind resistance and heat buildup during warm rides; reinstalling it restores full-face coverage for cold, wet, or high-speed conditions.

• Tool-free detachable front mask for quick conversion
• Secure locking points to maintain structural integrity in full-face mode
• Lightweight ABS shell to keep added weight minimal when modular

What protection and safety certifications does it offer?

This helmet meets DOT FMVSS-218 requirements, combining a robust outer shell with an engineered EPS energy-absorbing liner to manage impact forces in a crash. The modular architecture is engineered to preserve certification-class protection in full-face configuration while offering convenience in open-face mode.

• DOT-certified construction for street-legal use in the U.S.
• Multi-density EPS liner for staged energy absorption
• High-impact ABS outer shell for abrasion and puncture resistance

How do the visor and ventilation systems perform for long rides?

The helmet features a large, removable clear shield for an expansive field of view plus an internal drop-down sunshield that flips down to cut glare instantly. Strategically placed intake and exhaust vents channel airflow through the liner, reducing heat and keeping the padding dryer and more comfortable on extended trips.

• Crystal-clear outer shield with easy removal for cleaning or replacement
• Built-in drop-down sun visor for instant glare control
• Multiple intake scoops and rear exhaust vents for continuous airflow

How is comfort handled for daily use and maintenance?

Interior comfort focuses on long-term freshness and fit: the removable liner is washable and replaceable, and sizing is offered across five precise sizes to suit many head shapes. The cheek pads and crown liner are shaped to stay secure at highway speeds while remaining comfortable for city commutes.

• Removable, water-washable comfort padding for hygiene and longevity
• Anatomically contoured fit available in S–XXL to accommodate men and women
• Includes a heavy-duty drawstring storage bag to protect the helmet when parked

Who is this for: Riders seeking a single helmet that adapts to different rides—commuters who switch between sunshine and rain, weekend adventurers who want both protection and open-air comfort, and couples or groups needing a unisex, DOT-approved option in several sizes. It’s a practical pick for anyone who wants certified protection combined with modular convenience and easy maintenance.
