JMC Yak Hair is a rare natural fibre of exceptional quality, used extensively for streamer wings and tails. Their length and silky softness enable the creation of strikingly realistic mounts, perfectly reproducing the movements of aquatic prey. Thanks to their natural suppleness and great resistance, they offer a fluid, pulsating underwater swimming action, ideal for tracking large predators. A noble and authentic material, a must for demanding riggers looking for volume, life and naturalness in their creations.
