RST Tractech Evo 4 Two-Piece Suit

RST Tractech Evo 4 Two-Piece Suit — Sport Textile, CE AA

The Tractech Evo 4 is RST's flagship textile sport suit. Jacket and matching trousers are sold together as a system, designed for track days and aggressive road riding.

Materials & Vegan Verification

500D ballistic nylon outer on the jacket and trousers. Stretch mesh panels at the upper back and inner leg allow freedom of movement. Internal lining is 100% polyester. All panel reinforcements — including the shoulder cap overlays and the knee zones — are synthetic nylon, not leather. Verified vegan. RST has been explicit that the Tractech Evo range uses no animal-derived materials in its construction. No leather patches, no wool elastic, no animal adhesives. Seam tape and zip pulls are synthetic.

Protection (EN 17092 Combined Class AA)

• CE AA certification for jacket + trousers used together (EN 17092 combined two-piece standard)
• CE Level 2 elbow and shoulder armor (included)
• CE Level 2 knee armor (included)
• CE Level 2 back protector (included — factory fitted)
• Hip protector pockets with CE Level 1 armor included
• Connecting zip: full-perimeter RST 360° zip system

Aerodynamics

The Tractech Evo 4's jacket has a subtle aero shaping at the upper back and shoulder — not a hump, but a sculpted panel that reduces turbulence. Pre-curved sleeves and legs suit a forward riding position. The suit is quick on circuit but also wearable on the road.

Verdict

RST hits the right value-to-protection ratio with the Tractech Evo 4. CE Level 2 armor everywhere plus a factory back protector at this price point is hard to beat. If you need a two-piece CE AA suit for mixed track and road use and want vegan-verified materials, this is where to start.
