I don't own a Darien, but I've put 22 years and something over a quarter-million miles on a Roadcrafter, so... yes, three of the four front pockets in my Roadcrafter leak a bit: the left upper one, and the two lower ones. What they have in common is that they're all closed with a flap held shut by Velcro. The right chest pocket has a zipper, and is absolutely water-tight. So my suspicion is that any leakage in the pockets has to do with the fastening system not keeping the pocket fully closed.
Whizzy brakes, no FD drain plug, what's not to like?
