Connection + Rigging
Welded Loops
Welded loops make rigging fast, easy and reliable. Cortland loops are strong, clean and durable.
Line Technologies
Built on more than a century of line innovation.
Cortland has helped shape the way anglers fish for generations. From early innovations in tapered fly line design to modern cores, coatings, tapers, materials, and braided line construction, our technologies are developed with one purpose: to make lines perform better on the water.
Some features change how a line casts. Some affect floatation, sink rate, handling, strength, or durability. Together, they help explain why Cortland lines feel and fish the way they do.
Fly Line Technologies
Cortland fly line technologies are designed around the way a line feels and performs on the water. That focus shows up in lines made for clean casting, controlled presentation, dependable handling, and consistent performance in the conditions they were built for.
Fly line technology is about controlling how a line behaves. Core, coating, taper, finish, temperature design, sink system, and material choice all affect how the line loads, shoots, floats, sinks, handles, and holds up through repeated use.
The result is line that matches the conditions, handles cleanly, and helps anglers stay in control from the cast through the presentation.
Casting
Taper, coating, and finish influence how a line loads the rod, shoots, and turns over.
Presentation
Floatation, tip design, and taper affect mending, drift, and fly delivery.
Control
Sink systems, temperature design, cores, and materials influence depth, handling, durability, and connection.
Material Construction
Polyethylene
Liquid Crystal lines are built with a blend of polyethylene compounds (PE) over a monofilament core resulting in the toughest, slickest-shooting, floating fly lines.
Strength + Pressure
X-Strong Core
Constructed with a tight weave and high pick count for extreme durability and maximum applied pressure.
Identification
Line ID
Lazer printing line identification for convenient size reference.
Slickness + Shooting
Shooting Technology
ST coating delivers a reduced friction performance with a glass-smooth finish and remains a key element in the slickness over its life span.
Hook-Setting Power
Grip Set
Designed to give the angler a better hook set when targeting large game fish or fish with hard mouths.
Low-Friction Finish
Heat-Tempered Surface Treatment
Process that incorporates extreme slickness additives. Seals out dirt and oils while maintaining an exceptionally low friction coefficient.
Floatation + Presentation
High Float Tip Technology
A proprietary blend of materials that keeps fly line tips and leaders floating high in complex currents.
Cold Saltwater Handling
Cold Salt Technology
A supple yet extremely durable saltwater coating allowing for a memory-free line in cold conditions.
Sink Control
Tungsten Tip Technology
Premium Tungsten material combines with unique tapers for fast sinking presentations.
Sink Rate + Durability
Reinforced Tungsten
Improved Premium Tungsten blend for extended durability and fast sinking attributes.
Cold Weather Handling
Cold Temperature
Ideal use in 30-50 degree (F) temperatures.
Warm Weather Handling
Warm Temperature
Ideal use in 50-70 degree (F) temperatures.
Tropical Performance
Tropical Temperature
Ideal use in 70+ degree (F) temperatures.
Leader Material
Top Secret
Top Secret is a highly abrasion resistant, supple material allowing for superior knot strength while remaining virtually clear under water.
Braided Line Technologies
Cortland’s work with braid goes back to Ray Smith’s 1932 patent for the first braided fishing line. Today, that focus shows up in modern braided lines with strength without unnecessary bulk, sensitivity without stretch, smoother handling, better color retention, and construction made for demanding use.
Braided line technology is about controlling that strength. Fiber choice, carrier construction, coatings, and finish all affect how the line manages on the reel, moves through guides, holds color, keeps sensitivity, and performs under pressure.
The result is line that handles cleanly, holds up in demanding conditions, and gives anglers confidence when pressure is on.
Strength
Fiber choice and carrier construction influence breaking strength, diameter, and pressure.
Sensitivity
Low-stretch construction helps anglers feel contact, movement, structure, and strikes.
Handling
Coatings, construction, and finish affect casting, line management, noise, and guide performance.
Handling + Castability
fibertech
Protection that bonds to the individual fibers, which stiffens and improves handling of the line. Lines cast farther and last longer without excess stiffness.
Color Retention
Colorlast
Provides the longest lasting color. Doesn't fade. Doesn't bleed.
Noise Reduction
Silent technology
Hollow 16-carrier braid decreases noise and vibration creating a silent presentation.
Strength + Sensitivity
HMWPE
High molecular weight gel-spun polyethylene fibers that are stronger than steel. Virtually no stretch for incredible sensitivity. Doesn't degrade in sunlight / UV light.
Strength-to-Diameter
Opti-Con
Optimum Construction. Braids that are built for optimal strength by assembling each pound test to minimize line diameter while maximizing durability.
Guide Performance
Guide Protection
Designed to easily pinch through heavy cover.
Heavy Cover Performance
Punch Through
Proprietary construction that lays flat and does not damage rod guides.
