Sulphur hatches can be spectacular. A few hours of constant rises. Parachutes allow the fly to sit flush with the surface and make it easier to see in fast currents and heavy hatches. This fly pattern can be fished as an emerger, dun, or adult spinner returning to the water.
Our go-to sulphur pattern for both duns and spinner falls. Amongst the riffles and naturals, the bright white post makes it extremely easy to see in lower light conditions.
