Key Features
Overview
The Klein Tools Flame-Resistant Cooling Hard Hat Sweat Band (FRCLKHHSWTBND4) brings evaporative cooling to the hard hat without giving up arc-rated protection. This is a flame-resistant cooling sweat band designed for electricians and other professionals in hot, demanding environments where FR clothing is required.
Most cooling bands are not flame resistant, which puts them off-limits for energized work. This band is made from FR fabric (50% modacrylic, 30% viscose, 18% aramid, 2% antistatic carbon), tested to ASTM F1506-22 with an ATPV of 11.9 cal, and Klein rates it suitable for CAT 2 environments per NFPA 70E.
Cooling comes from an active insert between soft fabric layers. Soak it in water for 60 seconds, wring it out and wear it for instant relief. It stays cool for up to 90 minutes, then reactivates with perspiration as you keep working. The soft outer fabric is more comfortable than cooling bands made with abrasive materials.
It attaches securely to Klein hard hat suspension systems with a durable hook-and-loop fastener. The gray band measures about 16-1/4" x 9-7/16" x 5" (41.3 x 24 x 12.7 cm) and weighs 1.4 oz (40 g).
Who should buy it: electricians, utility workers and industrial crews who need FR-compliant cooling under a Klein hard hat.
