## Description

RaceQuip Underwear Head Sock Balaclava SFI 3.3 Fire Retardant FR Single Layer Hood Black Large 433991

Review: Solid SFI balaclava at a fair price - Needed a certified balaclava for HPDE events and this one checks all the boxes without costing a fortune. It fits snugly under my helmet without bunching up and breathes better than some of the thicker options I tried. The SFI 3.3 rating is what the rulebook requires so there's no worrying about tech inspection. Good piece of safety kit that I reach for every track day.
Review: Ajuste comodo - Se ajusta muy bien
