Product Information
Full details
The HJC Adwatt 1.5 is a high-performance aero helmet engineered for triathletes and road cyclists seeking the ideal balance between aerodynamic efficiency, cooling, and long-distance comfort. Utilizing advanced wind tunnel testing and Venturi dynamics, this helmet excels in drag reduction without sacrificing airflow; however, users should note that the visor-based design requires careful handling to maintain optical clarity and structural integrity during transit.

FAQs
Can I use the Adwatt 1.5 without the shield?
Yes, the HJC Adwatt 1.5 is engineered to provide excellent aerodynamic performance and ventilation both with and without the visor attached.
How much does the helmet weigh?
The helmet weighs 260g (±10g) on its own and 320g (±10g) when the mirror shield is attached.
Is the padding machine washable?
We recommend hand washing the X-static pads with mild soap and air-drying them to ensure the fabric's integrity and antimicrobial properties remain intact.
Does this helmet come with a storage bag?
It comes with a premium protective case designed to safeguard the helmet and its visor when not in use.
What is the primary benefit of the Venturi dynamics system?
It uses pressure differences to actively pull cool air through the helmet and exhaust hot air, providing superior cooling without needing large, drag-inducing vents.
Troubleshooting
The visor keeps fogging up during rides.
Ensure your head position allows for consistent airflow through the frontal vents, or consider applying an anti-fog treatment specifically designed for motorcycle or cycling visors.
The helmet feels loose or shifts while riding.
Re-adjust the rear retention system and ensure the wide side dividers are pulled tight enough to sit just below your ears.
Odors developing after heavy use.
Remove the X-static padding and wash it gently with mild detergent; the antimicrobial material is designed to be cleaned periodically.

Setup, Compatibility & Care
To ensure the HJC Adwatt 1.5 remains in top condition, follow these guidelines:
- Fitting: Utilize the adjustable wide dividers to secure the straps against the jawline for a snug, aerodynamic fit.
- Visor Handling: When attaching or removing the mirror shield, ensure your hands are clean and avoid touching the inner surface to prevent smudges and scratches. Use a microfiber cloth for cleaning.
- Cleaning: The internal X-static pads are removable; hand wash them with mild soap and air dry to maintain their antimicrobial properties. Wipe the shell with a damp cloth.
- Storage: Always store the helmet in the included premium case when not in use. Do not store the helmet in direct sunlight or locked in a car during hot summer days, as high temperatures can degrade the EPS foam liner.
