i have one also
something that helped mine:
any opening in the jacket (cuffs mostly but also bottom and hood), i rubbed some gear aid seam sealer into the fleece just on the very edge where the fabric bends and just enough to saturate the fleece exterior so water doesn't move through that area
otherwise, the fleece being continuous from the outside and curving into the interior (unbroken by a barrier) allows water to wick into the inside of the jacket in a decent rain
i figured this out after water wicked into the cuffs and my polypro top absorbed like 1/2 gallon of water
