Each RIO Powerflex knotless tapered leader is designed for superb abrasion-resistance as well as high knot and tensile strength. The long, thick butt design provides smooth turnover while the supple tippet gives the fly life-like presentation. RIO Powerflex is recommended for tippet material which gives the best knot strength.

For streamer fishing 1X/2X is a good choice. For dry fly fishing try 3X/4X leader or smaller if you are using small flies.

All Trout leaders have a perfection loop on the butt, which makes it easier to attach a leader to the fly line. Light gray color of the leader is the most neutral and integrates visually with any background for perfect camouflage.

Here are more detailed properties of the leaders.

The leader is 7,5 ft (about 2,3 m), 9 ft (about 2,7 m) or 12 ft (about 3,7 m) long. 

One leader per package.
