Buying Nylon Line?

Nylon line is a popular choice for many types of fishing. Even though superlines are superior in several aspects such as strength and flexibility, nylon line has several other valuable properties. Its stretchability is a significant advantage in some situations, for example when battling big fish. Another benefit is its high abrasion resistance, for example during salmon and sea trout fishing in rocky rivers. Other examples where the nylon line excels include float fishing, trolling, big game fishing, and ice fishing. There is also a more durable variant "hard mono", which works excellently as leader material for predator fishing.
Remember that nylon line is a perishable good, as the sun's UV rays degrade nylon in a relatively short time. So store the line in a dark and cool place, then it will remain fresh for several years.
