When you're suited up and strapped in, what's underneath matters. The Alpinestars FR Short Sleeve Top is a fire-resistant base layer built from 180g 100% Nomex/Meta-Aramide fabric — the same inherently flame-resistant material used across professional motorsport. It's designed to sit comfortably against the skin for extended sessions without the heat buildup or irritation that comes from lesser base layers.
Kevlar-reinforced thread gives the garment added durability while contributing to a noticeably softer hand feel — an important detail for drivers who spend hours at a time in contact with the suit. Flat seam construction eliminates the raised stitching that causes hotspots and pressure points, and the interlock wave construction adds stretch and breathability where the body needs it most. The crew neck and short sleeve profile keep it straightforward and compatible with any suit setup.
One important note: this top does not carry FIA or SFI homologation. It is well-suited for testing, practice sessions, track days, and series that do not mandate certified FR underlayers — but drivers competing under regulations that require homologated base layers should confirm compliance before race day.
