Ahi's unique formula of resins and coatings creates a supple yet exceptionally strong exterior, providing a superior abrasion resistant line.
Ahi GT4 is formulated for strength and sensitivity. The dense construction gives it 30% less stretch than monofilament which reduces memory and increases sensitivity.
The exterior finish of Ahi GT4 offers flexibility and low line memory for optimum casting, bait presentation, as well as superior knot and crimp strength.
GT4 is constructed using only the highest PVDF materials resulting in a fluorocarbon line that holds a similar refractive index property as water making it nearly invisible.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
