To the New Frontier of Nylon for Area Trout
●The Conclusion: “Pure”
A nylon that blends seamlessly into tackle built with ester lines.
As development progressed toward an extremely high goal, every raw fiber and processing method was tested, and days of trial and error continued.
Amidst this, one hypothesis emerged:
What if we used “thoroughly engineered hard nylon” in its “pure” state, deliberately avoiding further processing?
Testing this hypothesis led to the birth of “Masu no Ito Nylon,” which brilliantly delivered the expected performance.

●The enduring fascination of nylon
No matter how tough the line becomes, nylon's inherent fascination remains unchanged.
Its trouble-free nature compared to ester lines and its knotless, comfortable feel are still very much present.
Possessing reliable information transmission alongside these qualities, “Masu no Ito Nylon” is the ideal line not only for experts and competitors, but also for beginners and intermediate anglers seeking to discover the joy of area trout fishing.
・Modern area trout fishing isn't impossible with just ester. However, when you start targeting fish with deeper thought, there are fish you simply can't catch with ester alone.
・This is where nylon line becomes necessary. Yet, standard nylon lines are often avoided because their feel differs too much from ester, potentially reducing the fish you catch.
・After years of prototyping and field testing to achieve this ideal, we arrived at the conclusion: “Pure.”
・After testing every possible treatment, the ideal feel was achieved through the counterintuitive approach of “applying no treatment.”
・Includes size stickers for reel labeling. These stickers are exclusive to Masu no Ito Nylon, making it instantly distinguishable from other Masu no Ito products.
・Features a center marking (blue) at the 80m point.
