The SKB iSeries Waterproof Wireless Mic Case protects your wireless mics and receivers when traveling. Dense PE foam cradles your wireless systems while protecting them from shifting and hard knocks. The case itself is built from injection-molded polypropylene copolymer resin and can be retrofitted with TSA-approved trigger-release latches. And the iSeries Wireless Four-mic Case has a waterproof design that self equalizes to water pressure in case it takes an unfortunate dive. Many of us here at GearNuts rely on SKB cases in our own rigs, so you can be confident in your decision to add an iSeries Waterproof Wireless Mic Case to your equipment.
