FR Winter Liner — 17 cal Protection, Head-to-Neck Coverage Cold weather on the job shouldn't mean choosing between comfort and compliance. The FR Winter Liner pulls over your head and covers your face, neck, and chin in 10 oz 100% FR cotton knit — substantial enough to seal out the cold, rated for the work. With a 17 cal/cm² arc rating (ATPV) — CAT 2 — NFPA 70E, CSA Z462, and CGSB 155.20 — it layers cleanly under your FR outer layer for a fully compliant cold-weather system.
