Product Information
Full details
The RST S1 Mesh D3O Motorcycle Trousers are designed for adult male riders who prioritize a balance between safety and ventilation during warm-weather road riding. By combining durable full-grain leather in high-impact zones with high-flow mesh panels, these pants provide CE AA-certified protection without sacrificing comfort. While they offer excellent airflow and impact absorption through integrated D3O armor, riders should note that they are specialized for warm conditions and do not include thermal or waterproof liners, necessitating additional gear for cold or wet weather.

FAQs
Are these trousers waterproof?
No, these are mesh and leather trousers designed for maximum airflow in dry, warm conditions.
Can I use these for track days?
Yes, they feature replaceable knee sliders and meet CE AA certification, making them suitable for track use.
Does the armor come pre-installed?
Yes, CE Level 1 D3O armor is included in both the knee and hip pockets.
How do I ensure the correct fit?
Measure your waist at the widest point where you would normally wear trousers and match it to the UK sizing provided.
Can I connect these to any jacket?
The 360° zip is compatible with most RST jackets; if your jacket has a different zip style, you may need an adapter.
Troubleshooting
Armor feels stiff or uncomfortable
D3O armor is temperature-sensitive and softens with body heat; allow a few minutes of riding for it to conform to your body.
Difficulty zipping to jacket
Ensure the zip teeth are clean and free of grit; align the tracks carefully before pulling the slider to avoid snagging.
Leather feels too tight
Leather will break in slightly over the first few rides; check that you are not wearing overly thick base layers that restrict the fit.

Setup, Compatibility & Care
To ensure the best experience, attach the trousers to your jacket using the 360° connection zip before heading out to ensure the suit acts as a single, cohesive unit. When sizing, remember that the leather may feel snug initially but will settle with use; ensure you measure your waist accurately according to the UK size guide.
For care, avoid machine washing the leather. Clean the surface with a specialized leather cleaner and a soft cloth. Ensure the mesh panels are kept free of debris to maintain airflow. If the armor is removed for cleaning or adjustment, ensure it is seated correctly in the internal pockets before your next ride.
