The Ultralight floating fly box is made of moulded foam with micro sites in the inside of the box. this design allows flies to be backed into the box and protects the foam unlike regular foam boxes. Flies are held much better in this box and if this box is dropped into the water, it floats and is easily retrievable. The closure system is a magnetic closure and is handy enough to fit into a pack or a vest.
