OMP Tecnica FIA 8856-2018 Racing Gloves
The OMP Tecnica Racing Gloves provide FIA-certified fire protection, precise steering-wheel feel, and dependable comfort for demanding motorsport applications. Their anatomical, pre-curved construction follows the natural shape of the hand to help reduce fatigue during qualifying sessions, sprint races, endurance events, and performance track driving.
Multi-zone silicone grip material across the palm and fingers provides secure contact with the steering wheel, shifter, and paddle controls. A breathable, flame-resistant construction and flexible back panel help manage heat while preserving the close fit required for accurate cockpit control.
Certified to the FIA 8856-2018 standard, the OMP Tecnica is designed for drivers who need competition-approved protection without sacrificing sensitivity, flexibility, or comfort.
Pre-Curved Anatomical Fit
The OMP Tecnica features pre-curved fingers that follow the natural position of the hand around the steering wheel. This construction reduces resistance through the fingers and allows the driver to maintain a more relaxed grip during extended sessions.
The close anatomical fit also improves dexterity when operating paddle shifters, steering-wheel buttons, switches, sequential shifters, and other cockpit controls.
Multi-Zone Silicone Palm Grip
High-grip silicone material is strategically printed across the palm and fingers to provide dependable steering-wheel traction. The grip pattern is positioned to support the primary contact areas used during braking, cornering, shifting, and rapid steering inputs.
The low-profile silicone surface helps preserve steering feedback while reducing the amount of gripping pressure needed to maintain control. This can help minimize hand fatigue during long races and repeated track sessions.
Comfort-Focused Seam Construction
The Tecnica glove construction is designed to minimize uncomfortable pressure points around the fingers and palm. Its carefully positioned seams create a smooth interior feel while maintaining the durability required for repeated competition use.
This comfort-focused design is especially beneficial during endurance racing and other applications where the driver's hands remain wrapped around the steering wheel for extended periods.
Breathable Flame-Resistant Construction
Fire-resistant materials provide certified motorsport protection, while the breathable upper construction helps manage heat inside the glove. A flexible back section allows the glove to move naturally as the driver grips and releases the steering wheel.
The combination of ventilation, stretch, and close-fitting construction provides a balance of cooling, flexibility, and protection without adding unnecessary bulk.
Elastic Wrist and Pull Tab
An elasticated wrist helps hold the glove securely in place while maintaining a streamlined fit beneath the sleeve of a compatible racing suit. The integrated pull tab makes the glove easier to put on between sessions.
The low-profile wrist construction eliminates the need for a bulky external closure and provides dependable overlap with the racing-suit sleeve.
FIA 8856-2018 Homologated
The OMP Tecnica Racing Gloves are homologated to the FIA 8856-2018 standard for protective clothing used in automobile competition. This certification makes them suitable for many professional, amateur, club-level, endurance, rally, and road-racing applications.
