Our plugs caps feature a patented system that utilizes a hidden zippered tethering system to attach permanent, reusable certified NRR 27dB ear plugs. The plugs are easily removed for washing or replacement. The ear plugs extend from their side pockets when needed, and retract back into the hat when not in use. They are always there when you need them! Available in black with embroidered SIG SAUER Logo. Machine washable and weatherproof plugs and zippers. The cap has adjustable head strap to fit most head sizes.
