Sexy Walt Worms
This is hands down my go to favorite Walts variation. It's timeless for me. Should be on your line almost every time you euro nymph along with a frenchie or perdigon. Great anchor fly in larger sizes, but don't underestimate a size 18 walts for picky trout.

Available in sizes 12, 14, 16, and 18.

Now available in olive, and plain jane.
