Lightweight Cairns 360R-13 offers excellent protection when seconds count. The low profile design and light weight allow this helmet to shine in rescue and confined space usage. The brimless helmet features a Ultem thermoplastic shell and non-corroding, high-temperature, glass-filled polymer goggle hardware. The ultra high-temperature (TPR) edge trim won't melt or drip, and the Nomex chinstrap with one-hand quick release buckle and postman slide allows quick and easy adjustment. A choice of Nomex or Pbi/Kevlar earlap offers increased neck/ear protection, while 2- or 3-point chinstraps ensure a secure fit.
