Idon't know if you do this but i always soak my skirt in the rio before putting it on. it is almost impossible otherwise.. especially on my old villain. same skirt works for my 4fun, and superhero. its an NRS drylander /XL cockpit. definitely an adequate skirt, but not the best because its a bungee rand, and pretty tight. but its half the price too, and durable for sure.
really any brand as long as its at least XL cockpit, & keyhole shape.(pretty standard these days)
