For Mayfly Nymphs. 12 sets of non-toxic silicone legs, delivered with manual.

Perfectly measured and realistic legs for mayfly- and stonefly-nymphs. All colors and sizes are customized based on real nymphs and easy to use. The legs are seated on a sheet of silicone which is bonded as a whole. You never need to tie your legs individually or in pairs, you can tie all six legs together at the same time. The legs are also made of durable, stretchable and soft silicone, which makes the fish feel no resistance when it strikes, it experiences it as natural food.

Realistic Nymph Legs Stonefly is called S and is primarily used to imitate the nymph of stoneflies. But, it is also great to use for imitations of larger mayfly larvaes.

Realistic Nymph Legs Nymph is called N and is used to imitate mayfly nymphs.

However, the legs can be used to a variety of other fly patterns and it's only your own creativity that prevents you from creating them.

All sizes and colors are individually adapted to match natural nymphs. Each package contains sections of six legs to tie twelve flies. Instructions included.

N1 – fits hook size 6.
N2 – fits hook size 8.
N3 – fits hook size 14.
N4 – fits hook size 16.
N5 – fits hook size 18.

Instructions are included in each package.

Using the J:son system, you can tie realistic dry flies that leave a perfect impression on the water’s surface and are virtually unsinkable. Nymphs made with the J:son System have a natural silhouette and are taken for real insects. J:sonSystem flies are durable, so you can focus on the whole point of fly fishing, which is to fish.

When making wings, it’s possible to fuse a patterned wing material with a neutral one. This way, an air pocket is created between the two layers, increasing the fly’s floating ability. Regardless of whether your fly is used on the water surface, in the surface film or sub surface, the wings and wing buds will be very realistic in shape, color and structure. At the same time, they are extremely durable. The raw material for wings and wing buds consists of guaranteed toxic-free foil, and produces no harmful gas of any kind when burned. It’s approved by Swedish health authorities for use in the food industry. All J:son tools and materials are made in Sweden.

How to make wings

Trim excess material around the printed pattern (leave 1-2 mm for burning). Place in the appropriate wing burner and burn/weld the edges quickly with an open flame. You now have a perfectly shaped, realistic wing. The body of foam, the light weight and water surface tension all mean the fly will float like a dream. Use double wing material when tying larger flies. This creates an air pocket inside the wing, enhancing floating capabilities. Use a printed wing material and marry it with a neutral one. Trim excess material (leaving 1-2 mm for burning) around the printed pattern, place in the appropriate wing burner and burn/weld the edges quickly with an open flame. You now have a perfectly shaped, realistic wing that contains air, which – together with the body of floating foam – makes the fly virtually unsinkable.
