Effortless turnover and reliable knot strength for all your dry fly, nymph, and streamer fishing. Premium European-made 9-foot tapered leaders engineered to balance high knot strength with crucial shock absorption to protect light tippets.

3X (0.20 mm) – All-Round / Dry & Nymph

The J:son Ultimate Leader 3X (0.20 mm) is the ultimate all-round leader for classic fly fishing for trout, grayling, and Arctic char. It is delicate enough to offer a soft, natural presentation of medium-sized dry flies (sizes 10–14), while retaining enough backbone to handle weighted nymphs and smaller streamers. A must-have in your vest pocket during mayfly hatches.
