Sparco FIA/SFI Approved Cooling Underwear Top - White, Cooling Tubes On Front Only, XXL

Designed to work with a liquid-based driver cooling system, this FIA and SFI approved top helps regulate your core body temperature in high-heat race conditions to reduce fatigue and maintain focus. It features integrated cooling tubes and flame-resistant materials to deliver both thermal management and full motorsport compliance.Here s a breakdown of the key features, how they work, and the benefits you ll get from them:Integrated lightweight high-temperature tubing: Embedded throughout the top using a strategically routed layout, these tubes circulate chilled coolant from your cooling system to draw heat away from your body, helping reduce core temperature by up to 8°C and keeping you more alert and comfortable during intense sessions.Available with front and back or front-only tube layouts: You can choose between full-coverage cooling for maximum efficiency, or a front-only layout that avoids tubing on the back to prevent pressure points when seated, giving you better comfort depending on your seat setup and preference.FIA 8856-2018 and SFI 3.2A/5 approved construction: Manufactured from flame-retardant fabrics tested to meet current global motorsport safety standards, giving you full peace of mind when competing under regulated conditions.High-flow cooling path design: The internal tubing design has been optimised to allow high flow rates from modern driver cooling systems, improving thermal transfer away from the torso to help prevent overheating during long or high-temperature stints.Flatlock stitched seams: All seams are low-profile and lay flat against your skin to minimise pressure points under your race suit, reducing irritation and helping you stay more focused for longer periods.Lightweight flame resistant fabric: The base material provides a close and comfortable fit without restricting movement, ensuring the cooling system remains in optimal contact with your body even as you move around in the cockpit.High cockpit temperatures combined with long stints can quickly lead to physical fatigue and mental slowdown if heat isn t properly managed. When used with a liquid driver cooling system, this top actively helps lower your core body temperature, relieving the physiological strain that builds up during hot races. By reducing internal heat stress, it supports clearer thinking and more consistent lap performance, especially when heat soak becomes a factor. The choice of full or front-only cooling tube layouts also lets you tailor the setup without sacrificing comfort.If you're looking to maintain focus and control in high-heat race conditions, this top gives you a proven way to reduce your core temperature and delay fatigue. Pair it with a compatible cooling system to help you stay physically composed and mentally sharp from lights out to the final lap.SizesS - 34" to 36" chest (86-92cm)M - 36" to  38" chest (92-96cm)L -  38" to 40" chest (96-102cm)XL - 40" to 42" chest (102-108cm)XXL - 43" to 45" chest (108-114cm)FIA 8856-2018 and SFI 3.2A/5 approved
