DescriptionThe whole story▼
Long sessions demand a suit that works with your body, not against it — and the RST Tractech EVO D3O one-piece leather suit in Black/Red is built precisely for that. Combining an AAA-certified protection package with a removable Quick-Dry Stretch-Mesh lining, neoprene comfort zones and pre-curved knee panels, this sixth-generation race suit is engineered to keep you comfortable and in control from the first lap to the last.
Key Features
- AAA-certified protection with D3O Level 2 armour at shoulders, elbows, hips and knees
- Removable Quick-Dry Stretch-Mesh lining for a fresher, more comfortable interior climate
- Panel-in-panel perforated leather for improved airflow during high-intensity riding
- Motion Panels and pre-curved knee sections that support natural riding posture across long stints
- Neoprene Sport Comfort zones at collar and cuffs to reduce friction and hot spots
- Airbag-compatible construction for riders who want the option to upgrade their safety system
- Aerodynamic race hump, Shoulder Cups and Quick-Release loop-and-hook knee sliders for genuine track-day performance
All-Day Comfort in a Race-Ready Package
The sixth generation of the legendary Tractech EVO series focuses on ergonomics as much as outright protection. Improved pre-curved knee sections reduce fighting the suit in an aggressive riding position, while Motion Panels allow your legs and torso to move freely without pulling or binding. The Neoprene Sport Comfort collar sits softly against the skin, and the removable Quick-Dry Stretch-Mesh lining wicks moisture away during long track sessions or hot summer rides. Whether you are completing a full track day or covering fast B-road miles, the fit works with you rather than demanding constant adjustment.
AAA-Certified Protection Where It Counts
The Tractech EVO D3O earns its AAA rating through a thorough protection package that covers every primary impact zone. D3O Level 2 armour is fitted as standard at the shoulders, elbows, hips and knees — with dedicated pockets for an optional back protector and chest protector should you wish to add further coverage. Double leather layers reinforce high-impact areas, and every seam uses bonded nylon thread with a triple-stitch construction for exceptional tear resistance under load.

Premium Perforated Leather for Ventilation and Durability
The outer shell is constructed from Premium Drum Dyed Cowhide and AST-Pro — a combination that delivers outstanding abrasion resistance while retaining a supple, broken-in feel from the outset. Panel-in-panel perforated leather sections promote airflow across the chest, back and limbs, making this suit significantly more bearable on warm track days than a fully solid-leather alternative. The result is a race suit that does not force you to choose between protection and breathability.
Race-Spec Details for Serious Riders
This is not a crossover suit designed to compromise between road touring and occasional track use. Every detail on the RST Tractech EVO D3O points towards serious performance riding. The aerodynamic race hump reduces turbulence at speed, Shoulder Cups add a further layer of protection on the outer shoulder, and Quick-Release loop-and-hook knee sliders make paddock changes fast and tool-free. Zip fastening ensures a secure closure, and full airbag compatibility means the suit is ready to accept a compatible airbag vest without modification.
