The Big One is so called because we believe it is not only a U.K first but a world first when it comes to the size of the bottle. The Big One contains the same great ingredients Hunt's use in their original floatant, but now in a 2oz bottle. The concept for this came about due to the feedback Hunt's received from guides and frequent anglers alike. Many felt that the standard 1oz bottles previously available were quickly running out and when your fishing the hatch of a lifetime you need a product you can rely on. The Big One not only guarantees the same great performance, you now receive twice the powder for less than twice the price!
