The H2O Outdoor Gear Technical Radio Pouch is built to perform well in the worst of conditions and is quality handmade in the USA. With its inception in the Chugach Range of Alaska, it is designed so that the mic is positioned well under a 3-layer mountain shell jacket providing smooth, clean and crisp sound. This also acts as a filter around helicopters, strong wind and even enables the skier to speak clearly as he's riding to the rendezvous, keeping critical communication alive and effective. This also allows the batteries to stay warm providing long lasting power. The adjustable pocket adjusts to the size of any radio large or small and its snug, ergonomic fit minimizes impact related injuries.
