Umpqua’s XS420 BN5X Flats is a saltwater hook for flats patterns. It has a straight eye and a standard shank length, so it suits a lot of common saltwater fly proportions without forcing a specific silhouette. The XS420 is listed as extra strong with a needle point, and it’s finished in Umpqua’s BN5X corrosion-resistant black nickel for better hold-up in salt.
Across the sizes we stock (#01 down to #08), the layout stays the same. You’re mainly choosing gap and wire strength relative to the fly size and the fish you’re tying for. 20 hooks per pack.
