The Marshmallow Hopper one of Rainy's first original designs and one of the first hoppers to ever have foam incorporated into the fly!
Not only does it have a foam body, but a decent sized white foam parachute post (how it got its name) which also aids in floatation. The fly has a dark brown rib on the belly and barred round rubber legs for optimal attraction in the water. You can dead drift this fly or skate it across the water with a few strips here and there or the twitching of your rod tip.
This is one of the all-time great time-tested hoppers available on the market.
