The Story
A complete lineup of fly lines developed for the striped bass angler.
RIO’s Mainstream Striper fly lines are made specifically for striped bass and coldwater saltwater anglers. The line taper is quick-loading and easy casting, and is suited for a variety of fly sizes from large baitfish imitations to small crab patterns. The lines are intermediate density, sinking at 1.5 to 2 inches per second, are entirely clear for stealth while fishing, and also include a neat welded loop on the front end for fast rigging. Each Mainstream line is made in RIO’s Idaho manufacturing facility.
• Powerful weight-forward taper for casting a variety of fly sizes
• Clear, intermediate sinking configuration
• Welded loop on the front end for fast rigging
