Beyond his property to be invisible in water, this product is totally waterproof, and this means that it’s abrasion free, UV safe and even oil and alcohol proof, so that it can’t be harmed by flavours and liquid additives. Even though it’s softer than most common Fluorocarbon materials, FX Link is heavier than nylon, so it sinks well, sitting on the bottom to create unobtrusive rigs. Consequently, rigs made from this product won’t spook wary carp at all.
