The extra-absorbent, professional fabric picks up paint and then releases it more than any other cover. The Polar Bear is great for knockdown plaster, stucco and cinder or cement block. It reaches into textures and uneven spaces for complete, fast coverage and puts down a very nice finish on drywall too. Works on standard-size roller frames. The Polar Bear has long life and performs consistently day after day and the soft and silky fibers make it easy to clean.
