X-Series XS415 BN5X Backcountry Fly Tying Hook Hook and hold the toughest of saltwater fish. While specifically designed for Tarpon, this is a great all-around saltwater hook (think Deceivers and Clousers) that consistently gets big fish to the net. A large gap, sticky point and special BN5X finish put this hook above the competition. Only from Umpqua, the BN5X black nickel finish is up to 5X more corrosion resistant than standard BN finishes. Straight Eye, Wide Gape, Extra Strong, Needle Point, BN5X finish (super corrosionresistant black nickel)
