Underwear Top SPORT-TX White X Large SFI 3.3

The Underwear Top SPORT-TX White X Large SFI 3.3 is a purpose-built racing undershirt designed for drivers who demand fire protection without compromising comfort during extended track sessions or competition. Built to meet SFI 3.3 safety standards, this garment serves as a critical barrier layer beneath racing suits and multi-layer racing apparel. Whether you're running road course events, drag racing, or circuit competition, this base layer provides the thermal and fire-resistant protection that sanctioning bodies require.

Constructed from SFI 3.3 certified fire-resistant fabric, the SPORT-TX white colorway reflects heat while the engineered weave construction allows moisture management during high-stress driving scenarios. The X Large sizing accommodates layering over standard undershirts or can be worn as a standalone base layer, with a lightweight profile at just 0.6 lbs that won't add bulk under your racing suit. This undershirt is essential for any driver running sanctioned competition where SFI-rated base layers are mandatory or strongly recommended.

The design ensures breathability for all-day wear, making it a durable investment in your safety protocol rather than a consumable item. Drivers will appreciate the comfort and protection this undershirt provides, allowing them to focus on performance without distraction. Ideal for various racing formats, it meets the rigorous demands of competitive motorsport.
