Established in the UK in 2014 by Tom Hunt, the Hunts brand is a comprehensive range of fly and leader treatments including premium quality desiccants, floatants and sinkants for use when fly fishing.
 
Hunts Original Mud Line Degreaser should be applied to your tippet in order to eliminate any grease, allowing it to sink, and by using Mud in this way you will also reduce any line flash, allowing you get that fly closer to those easily spooked fish.
