Yak hair is one of the most underrated materials for big predator flies — and one of the hardest to find in Europe. Here's how we use it to tie a 25–30 cm streamer that still casts like a dream.
Why yak hair?
Yak hair is an excellent substitute for long synthetic fibers. It's long, durable, softens when wet and has a natural curve that creates a full, lifelike profile in the water — with less material. It sheds water easily and is slightly translucent. Combined with bucktail, it's the perfect material for tying large predator flies that stay surprisingly easy to cast.
Unfortunately, yak hair isn't easy to find in Europe. Luckily, ESOX stocks real yak hair in a wide range of colors — the only source of genuine yak hair in Finland.

Swipe through this step-by-step and tie your own 25–30 cm (or even larger) Yak Hair Streamer in your favorite colors.
Step 1 — Lay the foundation and the first bullet tie
Press the hook barb down and lay down a thread base. Start the first tie-in point just before the hook bend — roughly between the hook point and the flattened barb.
Tie in the bucktail facing forward, then fold it back to make a bullet tie. Aim for a high but narrow profile by pinching the sides at the tie-in point. You'll later use this “bullet” to your advantage to lift the yak hair and flash.
Remember: use super glue at every tie-in point to make the fly more resistant to teeth.
Step 2 — Blend the yak hair and flash
Blend the yak hair and Predator Flash together. Comb the fibers thoroughly and taper the tips. The amount of material shown in the picture is enough for the tail section only.
Step 3 — Tie in the tail
Tie the yak hair/flash blend on top of the hook with roughly 60–70% of the fibers facing backward and 30–40% facing forward. Keep the rear-facing fibers only on top and the sides of the hook (about 180°). Force the forward-facing fibers to spread under the hook and sides (again about 180°) with tying thread before folding them back. Secure the material all the way back to the previous bullet tie to create extra lift and hold the fly's profile.
Step 4 — Build the body
Build the body by wrapping Polar Reflector Flash, leaving roughly 2.5 cm (1 inch) of space for the last two tie-in points and the head.
Repeat Steps 1–3 to create the second tie-in point — a bucktail bullet tie topped with yak hair/flash blend — but use slightly more material than you did for the tail.
Step 5 — Check the profile
After Step 4, your fly should have a sparse, tapered body with a tall, narrow profile.
Step 6 — Shoulders and head
Make a high, narrow hollow tie with bucktail in front of the previous tie-in point to form the shoulders. This is usually where I change color. Add some Pike Dubbing in roughly a 60/40 ratio in front of the bucktail to build the head. Fold the forward-facing fibers back while working the thread through the dubbing, then finish the fly.
Step 7 — Eyes and finish
Hold the fibers back with a hair/material clip and attach the eyes with super glue. Finish the head with UV resin and cure it.
Once finished, wet the fly and hang it to dry — this will reveal the fly's final profile.
