Fins 40G : 15lb Braid
Kindly supplied for testing by the team at Salt Strong.
FINS 40G is the most unique braid on the market. 40G is a composite structure; comprised of an ultra high strength core which is very tightly overbraided with 8 ends of high tenacity gel-spun PE. Engineered to be extremely round and smooth and stay that way. Don’t let the mono-like feel trick you, this is a durable braid with the smallest diameter to strength ratio ever offered. FINS 40G is a real game changer!
