The Electronics Armband Case (Small) from Aquapac is designed to fit your small electronics and protect them from water damage. The case works best for small phones and micro-radios. It will fit electronics with less than a 6.0 (15.2 cm) circumference and 5.0 (12.7 cm) height. The case has a depth rating of 16.4' (5.0 m). The tough thermoplastic polyurethane casing protects your gear from dust, dirt and that most evil of contaminants - sand. Even if you aren't swimming but drop the case in water, it will float; but don't worry--the seams are all welded for additional protection. The armband can be used while running, swimming or simply to allow you to be hands-free to pursue activities such as surfing, kite-surfing, fishing or anything that revolves around water. The Aquaclip, a patented, secure, rustproof, injection-molded plastic sealing mechanism, is easy to use and opens and closes the bag via dual twist levers.
