I called wooster brush 1(800)392-7246 and talked tocustomer service. THEY DO NOT make this Microfiber roller cover for BM.Wooster has no plans to make one in the future either.It is probably made overseas in China as another company calledGAM (Great American Marketing) is just now bringing oneto the US to sell. It was supposed to be available in April butwas not. I do not know of any other manufacturer that is selling thatmaterial for roller covers. I have not used it so can't offer an opinionas to how the quality is.
The Wooster Polar Bear is a fabric cover... I love em for flats... holds and lays on a lot of paint without a heavy stipple.... I have not tried it with sheened paints....
