Help finding a girth

[StellaArtois]

Need help in finding a girth I have just got a new semi flex dressage saddle with normal length girth straps. The fitter suggested getting a girth that is not elastic as the semi flex saddle already has some give in it. Any ideas on type that is easy to clean and not too expensive.
Cheers

keiffer neoprene ones are fab, and not that pricey! about £30 i think, and washable too. they are nice and wide, and have the spring loaded buckles so u dont have to fiddle!
