The lightweight, eight ounce Economuff model features comfortable ear pads that ensure all-day wearing without fatigue and the durable design provides protection in tough, dirty environments. The Multi-Position muff has all of the features as our Economuff model, plus it incorporates a support strap used when wearing the muff behind the head or under the chin. The NRR is also much higher than the Economuff unit at 24 dB.
