Great snug fit to the saddle and does not move. Waterproof as advertised is true. Looks neat.
Perineal nerve is not protected and will depend if your existing saddle has a cutout for the same. Softness is not any better than the decathlon memory foam saddle cover. Overall good; however if I need to cycle indoors on a trainer and choose a saddle cover, then would rather be seated on a decathlon seat cover than this.
