Xstream can provide you with a first class backing. Thin diameter makes it possible to contain the adequate amount of security on your fly reel, in case that giant fish from your dreams, takes the fly, and runs off.
Xstream backing has low stretch, and is made from waterproof fibers to prevent it from rotting. We carry the classic two sizes of backing, namely 20 and 30 Lbs. For your convenience it comes in 3 different lengths – 90m, 275m and at bulk size of 2300 meters.
