I came across Blue Steel anti-chafe cream whilst in South Africa - I think it's only available in shops in the Southern Hemisphere. Remarkably though if you order from the manufacturers direct
then it still competes on price per weight when compared with Bodyglide, Chafe-Ease, etc. (Particularly when they have a buy one get one free offer that I just missed!)
Although not as cheap as Vas this is a water washable product and has worked very well for sweaty old me right up to 50km races. It does contain lanolin which some people are allergic to, however.
