Freshwater Monofilament Line

Izorline XXX Super Copolymer Smoke Fishing Line— 1/4lb Spools

When you need a line that disappears in the water column and holds up under pressure, Izorline XXX Super Copolymer Smoke delivers. Engineered with next-generation space-age additives, this monofilament packs exceptional strength into a small diameter — giving you more line on the spool and a stealthy edge over wary fish.

The smoke color is purpose-built for low visibility, making it a go-to for targeting sharp-eyed species like yellowtail, white seabass, and tuna. Whether you're fishing the surf, jigging offshore, or chasing trout in freshwater, XXX Copolymer performs where it counts.

The Line SoCal Anglers Trust

Izorline XXX has earned its reputation on the water — not in a marketing brochure. Veteran long-range and local sportboat anglers have relied on it for decades because it delivers where it counts: small diameter for more line on the spool, exceptional knot strength, and a smoke color that disappears in the water column. If you're fishing yellowtail, tuna, or white seabass, this is the line that won't let you down when the fish of a lifetime is on the other end.

What Makes XXX Different

Izorline engineered the XXX formula with space-age copolymer additives that push monofilament performance beyond what standard mono can deliver. The result is a line that's simultaneously limp enough to cast effortlessly, strong enough to handle hard-running pelagics, and tough enough to survive the rocks and structure where big fish live.

• Xtra Limp — soft, easy to tie, minimal coil memory off the spool
• Xtra Strong — Izorline's strongest mono formula, with high knot and tensile strength
• Xtra Tough — excellent abrasion resistance for rocky structure and kelp
• Smoke color — low visibility in the water column, a proven edge on pressured fish
• Small diameter — more line per spool, better bait presentation

When Line Visibility Costs You Fish

Clear water and pressured fish are unforgiving. Heavy, stiff, or high-visibility line kills bait action and spooks wary fish — especially white seabass and finicky yellowtail. The XXX's smoke color and ultra-limp formula let your bait swim naturally and your line stay out of the picture. It's the difference between getting bit and watching the fish swim away.

The Right Choice If…

• You're fishing live bait on local or long-range sportboats
• You want a mono that casts smoothly and ties clean knots without stiffness
• You're targeting clear-water species like white seabass, yellowtail, or tuna
• You need maximum yardage on your reel without stepping up in diameter
• You've been burned by cheap mono that breaks at the knot or loses strength after a few trips

At Home In These Situations

• Live bait fishing for yellowtail, tuna, and white seabass
• Slow-trolling and drift fishing on local and long-range trips
• Jigging and iron fishing as a main or backing line
• Freshwater applications where low-vis and low-memory matter

Best Conditions

• Clear saltwater — inshore, nearshore, and offshore
• Long-range and overnight sportboat trips
• Kelp and structure fishing where abrasion resistance is critical

Best For

• Yellowtail, bluefin tuna, yellowfin tuna, and albacore
• White seabass and calico bass on live bait
• Freshwater bass, trout, and general light-tackle applications
• Anglers who want a premium copolymer without the premium price tag

Models & Specs

Tackle Express Tips

• Spool under light tension with water or a damp cloth to reduce memory and ensure even lay on the reel — especially important on larger capacity reels.
• The smoke color is most effective in clear, blue water. If you're fishing green or murky water, the visibility advantage is less critical — but the strength and limpness still make it a top pick.
• For long-range trips, the 1lb spool gives you enough line to fill most conventional reels and have backup. Buy two if you're spooling a large-capacity reel like a Talica 20 or 25.

FAQ

Is Izorline XXX a monofilament or fluorocarbon?
It's a super copolymer — a step above standard monofilament in strength and limpness, but not fluorocarbon. Many anglers use it as their main line with a fluorocarbon leader for the best of both worlds.

What reel sizes does the 1lb spool fill?
Capacity varies by test strength. The 20lb/2,670yd spool will fill most mid-size conventional reels. Refer to your reel's line capacity specs and the yardage table above to match the right test to your setup.

Can I use this line for freshwater fishing?
Yes — the low memory, small diameter, and smoke color make it an excellent choice for freshwater bass, trout, and other species where line visibility and castability matter.
