These are a great item to dry your fly with. They take up little space and they hold flies well. The materials are high quality and while a bit expensive these are very well made. The Magnetic-ique products can be attached anywhere on your vest, pack or waders magnetically by placing the MAgMini and MagHub on opposite sides of the material. It’s the best way to store and dry your flies while on the water. Magnetic-ique products are made in the United Kingdom to the highest standards, using neodymium magnets and non-corrosive steel (CR12). We stock the Mag double and the Mag Single with Lanyard attachment.
