Silicone tubing

This silicone tube has a multitude of uses, but the most important is to hold the hair in place on your hook. It comes in two versions—0.5mm and 0.75mm—so it fits any hook size and any diameter of hair material, ensuring it has sufficient grip yet slides down the shank as needed once a fish is hooked. It's Weedy Green and comes in 1.5m in a pack.
