The WD-40 Gray Nymph Fly is a timeless, fish-catching pattern designed by Mark Engler and refined by top anglers worldwide. Known for its subtle and natural appearance, the gray variant is especially effective in clear-water conditions where trout feed selectively on tiny Baetis (BWO), Trico, or Midge nymphs.

With a slim, translucent profile and soft dubbing that mimics emerging insects, the WD-40 Gray drifts naturally through the water column — an irresistible trigger for wary trout. This pattern shines during tough hatches, pressured waters, and cold-weather fishing when presentation and realism are key.

Whether fished on its own, as a dropper below a dry fly, or in a Euro nymph setup, the WD-40 continues to be a go-to fly for anglers across all skill levels.

Available in sizes 18, 20, 22, and 24, the WD-40 Gray is professionally hand-tied with premium materials for durability and consistency.
