DescriptionThe whole story

Wearing a helmet all day should never feel like a compromise, and the Just1 J-STR Avalon in Turquoise / Gloss Black is built around that principle. Its generously padded interior — treated with Protx2™ antimicrobial technology, fully removable and machine-washable — keeps you fresh and comfortable from the morning commute to the long weekend run, while dual-certified ECE 22.06 and DOT safety architecture gives you the confidence to ride hard or ride far.

Key Features

  • ECE 22.06 and DOT certified safety platform with ABS outer shell in 2 shell sizes and EPS liner in 2 density sizes — tailored protection across the full size run
  • Protx2™ antimicrobial interior lining stays hygienically fresh; fully removable and washable for long-term comfort
  • Ergonomic cheek pads with the J.I.E.R. Emergency Cheek Pads Removal System — designed to assist first responders in safely removing the helmet after an incident
  • Wide Vision visor with scratch-resistant coating and Pinlock 70 ready port for fog-free riding in all conditions (Pinlock lens sold separately)
  • Double-D retention ring for a secure, stable fit during spirited riding
  • Efficient ventilation system keeps airflow moving to prevent heat build-up on longer rides

All-Day Comfort You Can Actually Feel

The J-STR's interior is one of the strongest arguments for choosing it over rivals at the price. The ergonomic cheek pads cradle your face without creating pressure points, and the Protx2™ antimicrobial treatment actively combats odour-causing bacteria — a real advantage if your commute or tour stretches into hours. When laundry day comes around, the entire liner system lifts out cleanly and goes straight in the wash, so the helmet feels as fresh on ride 200 as it did on ride one.

Visor and Ventilation

The Wide Vision visor opens up the field of view in a way that genuinely matters in traffic and on technical roads. The scratch-resistant coating stands up to daily use, and the Pinlock 70 ready pin system means you can equip an anti-fog lens at any time — useful as soon as temperatures drop or humidity rises. The nose cover included in the box channels breath away from the visor to further reduce misting. The ventilation channels work in concert with the visor system to draw cool air across the rider's face and exhaust warm air at the rear, keeping concentration sharp regardless of conditions.

Design

The Avalon graphic wraps the gloss-black ABS shell in a bold turquoise-and-black livery that reads as purposeful rather than simply decorative. The high-gloss lacquer finish is applied over the two-shell-size ABS structure, so the helmet proportions look right across the full XS-to-XXL size range rather than oversized on smaller heads.

Fitment and Sizing

The J-STR Avalon is available in six sizes to suit adult riders. Use a flexible tape measure positioned above the eyebrows and around the widest part of the skull — measure two or three times to confirm the reading, then match it to the table below. The helmet should sit firmly without pressure and must not shift when you push it sideways; if it moves, size down.

Size Head circumference (cm) Head circumference (in)
XS 53–54 20.9–21.3
S 55–56 21.7–22.1

“Two shell sizes and two EPS sizes at 1,520 g, with a double-D ring, emergency cheek-pad release and a fully vented chin bar — a proper specification for the money. Be aware of what is behind the score: nobody has measured this helmet independently, so those areas are left out of the total rather than guessed.”
