JammyPack Fanny Packs at Tilly's.JammyPack Background:JammyPack was conceptualized and created on the sands of Newport Beach, California and put to the test in the Rocky Mountains of Colorado. At the time, affordable-portable-durable audio simply didn't exist. In 2009 they set out to create the highest quality and most functional sound machine. After extensive development and testing, JammyPack was born and ready to storm the beaches, conquer mountains, and mob music festivals.What began as a product for the beach and the occasional escapade with friends, has grown into something bigger: Bridging the gap between Action Sports and Music, JammyPack embodies FREEDOM. A social tool designed for the perfection of the party, recreation, and frothy lounging.The above information is from the Jammmypack website.
