The single-sided SOLO offers tremendous versatility for the fly-fishing minimalist who wants to step into the water with as little gear as possible. Given the light-weight nature of the SOLO, it can easily be clasped onto the brim of a hat, attached to an existing landyard, or fishing pack. The steel plate can be placed inside a pack or fishing shirt, and the magnetized rubber mold will attach directly to the plate and stay in place.In addition, multiple SOLO's can be placed on most fishing packs making for multiple "oehot spots" for flies.
