I have a parka and bibs from the Cabelas Guideware line. I have been very satisfied with it. Looking at the BPS brand, it looks like the same stuff just different brand logo sewed on. It's expensive stuff but well worth it.
If you want another option, some of the catfish guys use this suite that a guy up North sales. The Dan suite? I don't know why but for some reason "Dan" keeps coming to my mind when thinking about it. Catfish guys can give you more info.
