This Waline nylon fishing line is invisible and made from a monofilament. It is available in different colours and weights and it has good knot strength. It is abrasion-resistant as well, so you can trust it not to break easily. It also has low friction when it is running through rod guides. It will even withstand the harsh conditions of being in saltwater. It has excellent tensile strength and a small diameter which means that it results in a larger reel capacity when fighting big game fish. It has low light reflection meaning that it is almost invisible in all types of water.
