TRIANGLE Convertible Modular Motorcycle Helmet DOT Certified — Black, ABS Shell & Drop-Down Sunshield

TRIANGLE's Convertible Full Face Motorcycle Helmet is a DOT-certified modular helmet that converts quickly between a full-face shielded position and an open 3/4 configuration for versatile, reliable protection on road or trail.

This helmet combines certified impact protection with user-focused features so riders can change configurations without tools and keep comfortable on long rides. Built with a sturdy ABS shell and multi-density EPS liner, the TRIANGLE modular helmet meets DOT FMVSS-218 standards while packing ventilation, a drop-down sunshield, and a washable interior. Whether you commute, tour, or explore backroads, the design aims to balance safety, visibility, and ventilation with straightforward operation.

How does the convertible design adapt to different riding conditions?

The helmet’s hybrid modular construction lets the front mask detach quickly so you can switch from a full-face sealed shield to a ventilated 3/4 layout. Conversion is tool-free and intuitive, supporting changing weather and visibility needs without carrying extra shields.

• Detachable front mask for full-face or open-face use
• Tool-free removal and reattachment mechanism
• Compact profile when in 3/4 mode for improved airflow
• Secure locking points to maintain structural integrity when closed

What safety features and certifications does this helmet offer?

Safety is built into the shell and inner structure: the ABS outer layer disperses impact energy while the multi-density EPS liner provides staged shock absorption. It is certified to the DOT FMVSS-218 standard, indicating it meets U.S. regulatory requirements for adult motorcycle helmets.

• Meets or exceeds DOT FMVSS-218 certification
• High-impact ABS outer shell for durability and force distribution
• Multi-density EPS liner for progressive energy absorption
• Secure retention system designed for highway speeds

How does the helmet manage light and airflow for rider comfort?

Visibility and thermal comfort are handled with a clear outer shield plus an internal sun visor for quick glare control. A network of intake and exhaust vents channels fresh air through the liner to reduce heat build-up, and the interior pads are removable and washable to keep the helmet fresh.

• Crystal-clear removable outer shield for wide, unobstructed vision
• Built-in drop-down sunshield for instant glare reduction
• Strategically placed intake scoops and exhaust vents for airflow
• Removable, washable comfort liners and cheek pads

What sizes and extras come with the helmet?

The TRIANGLE helmet is offered in five adult sizes to fit men and women with a contoured, secure shape. Each purchase includes a heavy-duty drawstring storage bag to protect the finish when not in use.

• Available sizes: S, M, L, XL, XXL for adult head shapes
• Anatomically contoured fit to maintain stability at higher speeds
• Replaceable inner padding for long-term use and hygiene
• Included protective drawstring storage bag for transport and care

Who is this for: Riders seeking a single helmet that handles commuting, touring, and occasional adventure will appreciate the TRIANGLE convertible DOT helmet. It suits motorcyclists who want DOT-approved impact protection with the flexibility to open up the front on warm days or during slow scenic rides, plus riders who value easy-to-clean interiors and an integrated sun visor without swapping lenses.
