RST S1 Mesh D3O Leather Trouser Black
The RST S1 Mesh D3O Leather Trouser Black combines premium leather protection with enhanced airflow for warm-weather motorcycle riding. Developed from RST’s popular S1 collection, these ventilated leather motorcycle trousers use full-grain leather in key impact zones and K300 mesh panels to help riders stay cooler without compromising essential protection.
Protection and comfort
CE-certified to Class AA, the trousers include D3O® Level 1 armour at the knees and hips for flexible impact protection. Four-way stretch panels, a fixed mesh lining and an elasticated waist support comfortable movement, while full-leg ventilation promotes airflow during warmer rides. A 360-degree connection zip allows secure attachment to a compatible RST jacket.
