The 12-pack of Umpqua Mini Leech Jig Radiant jig hooks is an ideal choice for river and stillwater fly fishing, where catching trout is the main focus. The hook's design features a natural horizontal orientation when in the water, allowing us to mimic the movement of smaller leeches, which are a common food for trout. As it moves through the water, it swims like the real thing, providing an attention-grabbing shimmer with eye-catching color combinations.
