Why this part
Single-layer SFI-1 and SFI-3 jackets are fine until your class rules or your risk level says otherwise. The two-layer construction here buys you real thermal resistance margin — the kind that matters when a fire lasts longer than a second. Simpson's reputation in motorsport safety is built on decades of sanctioned competition, not marketing.
