Assuming it's DWR (durable water repellant) coating on the shell fabric we're talking about, a trip through the clothes dryer should renew its water repellancy if you find water is no longer beading up. I seldom wash my down stuff, far less than fleece, so don't often have to do this. The WM website should have detailed care instructions; if not check somebody else like Feathered Friends.

Enjoy your new jacket!
