I bought the 34 short and they are the best fitting pant I have tried on as the D30 armour fits me spot on when seated on my bike. I am 5'8", 30 inch inseam, stocky, athletic build at 195 lbs and ride a 2011 r1200gs. These pants are great commuter pants and indeed waterproof. Easy to walk around in and easy to take off. My work required business casual so these pants were perfect for me as the they have zippers that go 3/4 of the way up for easy access.
Not sure about summer time use yet but would be nice if it had a rear vent to let air flow out as only having one zipper for venting will cause the pants to trap air and parachute. While extremely comfortable, not sure how the pant itself would survive in a crash as it isn't as heavy as a KLIM material. I have faith with the D30 armor doing its job but the pant may not repairable like how my KLIM latitude jacket is.
