Pyramex Skull Cap Liner - Black

Stay Dry Under the Hard Hat. All Shift Long.

Heat and sweat buildup under a hard hat is one of those discomforts that compounds over a long shift — distracting, uncomfortable, and potentially hazardous when sweat drips into your eyes. The Pyramex Skull Cap Liner in Black is a simple, effective solution: a moisture-wicking cap designed to sit comfortably under your hard hat, trap sweat before it reaches your face, and keep you focused on the work in front of you.

Moisture-Wicking Soft Fabric

Made from a soft, lightweight moisture-wicking fabric, this skull cap pulls perspiration away from your scalp and forehead, allowing it to evaporate rather than pool and drip. The result is a cooler, drier experience under the hat — especially valuable during hot weather work, high-exertion tasks, or extended shifts in warm environments.

UPF 45 Protection

Rated UPF 45, the skull cap liner provides solid protection against UV radiation for the skin it covers. For workers who remove their hard hat during breaks or work in partially exposed conditions, that added sun protection is a meaningful benefit.

Hard Hat Compatible — Third-Party Tested

This liner has been third-party tested and verified for use under ANSI/ISEA compliant Pyramex hard hats. It fits cleanly inside the suspension without affecting the fit or safety performance of the hard hat. Note: Not compatible with the SL Sleek Shell series.

One Size Fits Most

The stretchy, one-size-fits-most design accommodates a wide range of head sizes comfortably. It's low-profile enough to disappear under the hard hat without adding bulk or pressure points, and soft enough to wear all day without irritation.
