Loon Outdoors Henry's Sinket Fly Sinking Agent

Formulated for easy application to nymphs, soft hackles, emergers and other sub surface flies to help them break the water surface tension and sink naturally. Hydrophilic properties attract water causing your fly to behave like a natural aquatic insect emerger or to roll along the bottom as naturally as a drifting nymph. Biodegradable. 1/2 oz.
