Zoe Campbell –
I’ve used the Adams pattern for years and it’s still one of my go-to flies. It floats well and mimics the natural mayflies perfectly. The barbless design makes it easy to handle and retrieve.
Tracey Clark –
Great quality and consistent size. I use it during early morning hatches and it consistently gets bites. Works well in both still and moving water.
Donna Poole –
Solid pattern that performs well in typical mayfly hatches. A bit heavier than I expected, but still effective. Would recommend to any dry fly enthusiast.

The Adams is a classic. I’ve been fishing with it since I started and it still holds up well. The barbless version is a big plus for easy casting and handling.
