Grillo’s Bob Gnarly Mouse Fly: Trophy Trout Mouse Pattern

The grillo’s bob gnarly mouse fly is the most durable, fish-triggering mouse pattern ever created, born from Andrew Grillo’s Alaskan guide experience. Built with a strike indicator core and ultra-durable foam, this fly (size 4 standard) survives dozens of toothy strikes while creating perfect surface disturbance that drives big trout wild.

Why Alaskan guides won’t fish without it:

Indestructible design: Outlasts 50+ trout when other mice get shredded
Night-fishing beast: Throws massive wake in low light when big trout hunt
Self-righting magic: Always lands upright for immediate action
Trophy-tested: The #1 choice for Kanektok River 30″+ rainbows

Fish it like a pro:

• 7-8wt rods with 10lb tippet for bulldog strikes
• Aggressive strip-pause along undercut banks at dusk
• Dead-drift twitches through foam lines for subtle takes
