RST Tractech EVO D3O One-Piece Leather Suit – Perforated Race Suit | Women | Black | 103643

Built from premium drum dyed cowhide and AST-Pro leather, the RST Tractech EVO D3O women's one-piece race suit in black sets the standard for construction quality in its class. Every panel, stitch and protector placement has been engineered for riders who demand materials and craftsmanship that can genuinely be trusted at the limit — on track or on a spirited Sunday road.

Key Features

• AAA-certified construction with D3O Level 2 armour at shoulder, elbow, hip and knee for the highest category of protection
• Outer shell in Premium Drum Dyed Cowhide and AST-Pro for exceptional abrasion resistance, durability and a refined finish that lasts
• Triple-stitched seams with bonded nylon thread and double leather layers at all primary impact zones
• Panel-in-panel perforated leather sections improve airflow during warm-weather sessions without compromising structural integrity
• Removable Quick-Dry Stretch-Mesh lining keeps moisture away from the skin across multiple sessions
• Race-specific details include Aerodynamic Race Hump, Shoulder Cups, Knee Sliders, Motion Panels and Neoprene Race Comfort Collar

Premium Materials and Construction

The outer shell of the Tractech EVO D3O is produced from Premium Drum Dyed Cowhide — a process that saturates colour deep into the hide for long-lasting uniformity and surface resilience — combined with AST-Pro panels in areas requiring additional stretch and durability. The result is leather that looks as refined as it performs. All primary seams are triple-stitched using bonded nylon thread, and critical impact zones receive double leather reinforcement, adding structural depth precisely where a crash demands it most.

This level of material specification distinguishes the Tractech EVO D3O from entry-level race suits: the leather is not merely decorative but a functional, load-bearing part of the suit's protective system.

AAA-Certified Protection with D3O Level 2 Armour

The Tractech EVO D3O carries AAA certification — the highest category under the European motorcycle protective clothing standard — reflecting the integrity of its entire protective architecture. D3O Level 2 protectors are fitted at the shoulder, elbow, hip and knee, delivering class-leading impact absorption in the zones most exposed during a fall. A chest protector pocket and a back protector pocket are both included, allowing riders to upgrade to a full suite of body armour to their own specification.

Perforated Leather for Ventilation

Sustained track sessions generate heat, and the Tractech EVO D3O addresses this through panel-in-panel perforated leather zones that channel airflow across the body without weakening the shell structure. This ventilation strategy keeps the suit wearable across extended use while maintaining the abrasion protection that solid leather provides. Combined with the Quick-Dry Stretch-Mesh lining, the suit manages interior climate far more effectively than a traditional unperforated leather construction.

Ergonomics and Comfort

A women's race suit needs to move with the rider rather than resist her. Pre-shaped knee sections, flexible Motion Panels at articulation points and the Neoprene Race Comfort Collar at the neck opening all contribute to a suit that supports rather than constrains. The removable Quick-Dry Stretch-Mesh lining wicks moisture efficiently, maintaining comfort from the first lap to the last. The close-cut race silhouette is purpose-built for a committed riding position — hang-off, deep lean angle and aggressive cornering stance.

Race-Specification Details

The Tractech EVO D3O is equipped with the hardware that matters on circuit:

• Aerodynamic Race Hump for reduced drag at speed
• Shoulder Cups for additional shoulder structure
• Knee Sliders for lean angle reference
• Motion Panels for unrestricted movement through corners
• Perforated leather zones for warm-weather ventilation
• Double leather layers at all high-impact areas
