Trina's Squirm (Squirmy Wormy) combines a flexible core with a silicone gummy worm layer for lifelike action and serious durability.
If you've ever tied a squirmy worm pattern only to have it tear, fray, melt, or lose its action after the first hard take, you already know the problem Trina's Squirm solves. This new squirmy material is built for fly tyers who want lifelike water movement without sacrificing durability.
Developed by Montana Fly Company, Trina's Squirm features a hybrid design with a flexible core coated in a silicone gummy worm layer. That combination delivers the stretch and movement of classic squirmy materials, along with the strength of a chenille-like core.
In practical terms, it holds up better to thread tension and repeated fish strikes. It's engineered to help prevent common issues like tearing on the first strike, melting from heat or glue, or fraying during tying. You get realism in the water, but with far fewer 'what went wrong with the material?' moments at the vise.
Trina's Squirm is a great choice for San Juan Worms, Squirmy Wormies, and attractor nymphs. It's especially effective in off-color or high-water conditions where fish often key in on motion and presence more than fine detail.
Another advantage is compatibility: the material is safe to use with adhesives and UV resin, which makes it a convenient upgrade for modern fly tying workflows.
Whether you're tying your next batch for tough water or looking for a squirmy that lasts, Trina's Squirmy Wormy is a dependable option - one many anglers find to be the most durable squirmy material they've used.
