For the racers out there – this Zamp underwear top is an extra, important safety layer to wear under your fire suit. It's SFI 3.3 certified, which means it's made from fire-resistant materials (a blend of FR acrylic and cotton). It's a single layer, so it's lightweight and breathable, but it adds that crucial protection. The material has a plush feel against the skin, and it's designed with a tailored fit so it doesn't bunch up under your suit. The cuffs are larger to help prevent the sleeves from sliding up. It's all about comfort and safety, keeping you cooler and adding another barrier. Just throw it on under your suit for track days, autocross, or any racing event where you need that extra peace of mind. Size Large in classic black.
