FAQ
What's the difference between SFI 3.2a/1 and higher SFI ratings? The 3.2a/1 rating is the entry-level SFI standard. Higher ratings (like 3.2a/5) offer longer burnthrough times and are required by more competitive racing series.
Will a single-layer suit keep me cool? Single-layer construction does run warmer than two-layer, but the lightweight design helps manage heat. Many drivers prefer the minimal bulk for longer track sessions.
