In reply to Timmd:
Never found any grade of Wind Pro that passes the blow test (with the fabric placed against the lips, that is). Since there isn't a membrane, wind will pass. It uses a denser weave and textured face to achieve its wind resistance. Are you sure the gloves aren't Windbloc?
Powershield is an intermediate step between WindPro and Windbloc/Windstopper, and has a woven outer face. There are different grades, some allegedly having a perforated membrane between face fabric and fleece inner, but, since Malden's website doesn't give adequate details, I'm not sure about this. Also, Powershield is damned expensive - it's touted as a soft shell - need I say more?
You could, of course, just buy a simple pertex windproof to pop over the top of your existing fleece...
