In reply to leon 1:
Yes it should and does bead up if DWR in good order. All mine do except when the DWR is needing refreshed. There are occasional stories of faulty batches, so maybe yours is faulty?
As a quick test put a cupped hand part way into one of the sleeves and fill the cupped part with tap water. The water should remain in the cupped hand with no wetting out or soaking through. In practical real life use though there maybe some wetting out due to the pressure effect, wear of DWR, etc, but not usually if brand new.
Take it back if you are not happy or have doubts.
