VARIVAS Super Trout Katchi-iro 100 m nylon fishing line

Varivas Super Trout Advance Katchi-iro, a low-visibility nylon line for river trout fishing

Varivas Super Trout Advance Katchi-iro is a premium nylon fishing line developed specifically for lure fishing for trout in mountain streams and rivers. Its design prioritizes low visibility, knot strength and suppleness suited to light-tackle techniques.

Its distinctive reddish-brown color, called Katchi-iro, helps reduce the line’s visibility underwater—a particularly useful advantage when targeting wary trout in clear water.

Katchi-iro color for maximum stealth

The distinctive feature of Super Trout Advance Katchi-iro is its reddish-brown color, inspired by colors traditionally used on Japanese commercial fishing nets.

This color was chosen to make the nylon line difficult for fish to detect, particularly in natural mountain-river environments.

It is a real asset when targeting the wariest trout, including larger specimens that are especially hard to fool.

Suppleness designed for small lures

Varivas Super Trout Advance Katchi-iro has moderate suppleness, specifically designed for technical river fishing.

This feature helps preserve the natural swimming action of small hard baits, spoons and other lightweight lures without interfering with their movement.

The line also sits well on small-diameter spools, making it easier to use with spinning reels intended for trout fishing.

VA-G technology for improved knot strength

Thanks to the exclusive VA-G process, Super Trout Advance Katchi-iro offers improved knot strength.

This technology allows anglers to use a thinner diameter while retaining high strength, making the line less visible and giving lures a more natural presentation.

The thin diameter also reduces drag in the current and makes it easier to control lure action in fast-flowing or shallow areas.

A nylon line designed specifically for mountain rivers

Varivas Super Trout Advance Katchi-iro meets the needs of anglers fishing for trout with lures in small streams.

Its low visibility, suppleness and strength help anglers effectively fish challenging spots, including currents, riffles and pools where fish hold.

It is an excellent choice for anglers seeking a technical nylon line that preserves natural lure presentation while offering excellent reliability during the fight.
