RIO's new Saltwater Mono is the go-to choice for anglers looking to tie their own leaders for tarpon, bonefish, permit, and other saltwater species. The material has a great strength-to-diameter ratio, extremely good abrasion-resistance, lacks memory and provides incredible knot-ability. Available in size 8lb to 60lb, there is an appropriate diameter for any leader's butt section, plus a great range of sizes to taper down with. Each size comes with 50 yards of tippet on the spool
