The Vamper has been designed with vertical fishing in mind. Made out of a very soft material he will deliver subbtle vibrations at anytime. The belly slot offers several advantages, it's place that you can easily load with attractant when needed, but it also provides an even better softness to the whole body and will collapse when a fish bite. The Vamper has also a tail bump under the tail which add more weight at the very end of the body to enhance vertical movements. It can of course be used on a wide gap hook to target pike, bass, or even seabass.
