Why every fly fishing tool kit needs a Grippi Thumb Sleeve:

• Helps extend life of your fly line by continually keeping it clean.
• The sleeve features tough, high-friction silicone dots/nodules to prevent slippage on your line control hand when casting.
• No-slip strip strike.
• Use GRIPPI Thumb together with the SLIPPI
Finger to provide exceptional control of your fly line.This allows you to throw crisper, tight casts without losing control of a slick, wet line.
