ZX Evo Bottom V3 X-Lrg / 2X-Lrg Black Long Sleeve

The ALPINESTARS ZX Evo Bottom V3 X-Large / 2X-Large Black Long Sleeve is a professional-grade motorsports base layer engineered to meet SFI 3.3/5 and FIA safety standards. Designed for drivers who demand fire-resistant protection during high-performance driving, circuit racing, and endurance events, this bottom layer combines advanced flame-retardant technology with tactical comfort for extended wear in the cockpit or on the grid.

Constructed from Lenzing FR fabric, the ZX Evo V3 offers inherent flame resistance without compromising breathability or moisture management—critical for drivers facing hours of physical and thermal stress. The long-sleeve design provides full coverage and enhanced protection, while the fabric's properties help regulate body temperature under race suits and heavy gear. The SFI 3.3/5 and FIA approvals certify this garment meets international safety specifications for professional motorsports competition, making it a legitimate choice for sanctioned events where protective underwear is mandated.

This bottom layer is built for drivers competing in circuit racing, rally, off-road motorsports, and track days where fire-resistant base layers are either required or strongly recommended. The X-Large / 2X-Large size accommodates larger frames, ensuring proper fit and coverage without binding or excess material that can create hot spots under a race suit. The black colorway pairs seamlessly with any race suit or driving package and resists visible wear.

Fire-resistant base layers meeting SFI and FIA standards represent the benchmark for organized motorsports safety. ALPINESTARS' ZX Evo line is recognized across professional racing platforms, from regional club events to international competition. Drivers familiar with previous generations of ALPINESTARS thermal wear will recognize the V3 iteration as a refinement focused on durability, fit, and compliance with current safety regulations.
