The carp mattress with a particularly large surface, 100 cm long and 60 cm wide, protects the prey from physical and surface injuries. Its use is mandatory on most fishing waters, which is completely legitimate and expected of all anglers. By watering, we can protect the fish from internal injuries, as well as damage to the mucous membrane and scales, thus protecting the released fish from the appearance of later complications and diseases. Folded into three parts, it is not only a featherweight, but also a space-saving solution. Its size enables the placement of capital copies, yet its compact transportability makes this product an excellent option even for spinners.
