The Zoom Super Tube combines durability and softness, with a salt release system that causes fish to hold on longer by giving them a burst of salt when they bite down. They are hand-dipped, which provides a thicker, more durable body, along with perfectly cut tentacles. Try the smaller size on a jighead for smallmouth, pitched into a wary female's bed or flipped into a thick grass bed for cold front monsters. Salt impregnated. Sizes 3 3/4" and 4 1/4".
