TRIANGLE Convertible Modular Motorcycle Helmet DOT-approved — Full-Face to 3/4, Internal Sunshield

TRIANGLE's Convertible Full Face Motorcycle Helmet is a DOT-certified modular helmet that converts between a protected full-face and an open 3/4 configuration while offering an internal sunshield, removable visor, and washable comfort liner.

This helmet blends rugged safety construction with everyday versatility for riders who want one dependable shell for varied conditions. Built to meet DOT FMVSS-218 requirements, the helmet uses an impact-resistant ABS outer shell and multi-density EPS liner. The modular design lets you flip between configurations quickly, and a built-in drop-down sunshield plus a removable clear outer shield handle changing light without swapping lenses.

How does the modular system change the helmet for different rides?

The helmet’s detachable front mask converts the profile from a full-face to a three-quarter open-face setup in moments, so you can switch depending on comfort, traffic, or weather. The mechanism is tool-free for fast transitions and keeps secure when locked into either position.

• Tool-free removable front mask for quick conversion
• Secure locking design to prevent accidental opening
• Fits full-face for higher speed protection or 3/4 for airflow and visibility
• Compatible with the removable outer shield and internal sun visor

What visibility and eye protection features are included?

The helmet offers layered eye protection: a crystal-clear outer shield for full-face coverage and an internal retractable sunshield to reduce glare. The outer shield is removable without tools for cleaning or swapping, while the drop-down sunshade drops into place instantly to improve comfort in bright conditions.

• Removable, wide-view clear outer visor for unobstructed sightlines
• Internal drop-down sunshield to cut glare without adding lenses
• Tool-free shield removal for quick maintenance or replacement
• Large field of view designed for city and highway riding

How does the helmet keep you cool and comfortable on long rides?

Strategic intake and exhaust vents channel air through the shell to reduce heat buildup and move moisture away from the head. The interior padding is premium, fully removable, and washable to keep the helmet fresh; replacement liners are supported for long-term hygiene and comfort.

• Multiple intake scoops and rear exhaust vents for continuous airflow
• Multi-density EPS liner balances impact absorption with ventilation paths
• Removable, washable comfort pads for odor and sweat management
• Replaceable interior components to extend helmet life

What sizes and extras are offered with this helmet?

The TRIANGLE helmet is available in five adult sizes (S–XXL) with an anatomically tuned shape designed to stay stable at highway speeds. Every helmet ships with a heavy-duty drawstring storage bag to protect the finish when not in use.

• Available sizes: S, M, L, XL, XXL for men and women
• Anatomical fit to reduce wind lift and unwanted movement
• Includes protective drawstring storage bag for transportation and storage
• DOT FMVSS-218 compliance for highway-legal use

It suits adults seeking DOT-rated protection, modular convenience, built-in sun control, and removable, washable comfort for prolonged use. If you want a durable, adaptable helmet that keeps maintenance simple and visibility high without carrying extra shields or accessories, this helmet is designed for that purpose.
