Ended up with a pair of Tourmaster venture pants.
Great quality for price paid. The insulated liner is nice. They are a bit bulky, but I imagine all overpants are.
Took a spin the other evening. Temp was approx 28 degrees. Stayed out for an hour and my legs were plenty warm.
I'm about 5'9, 155 - 160ish lbs, 30 - 32" waist, 30" inseam (insert short joke here). I ordered the pants in a medium and the waist fits over my jeans thanks to the elastic on the hips. Length seems ok, but a bit long... which is probably a good thing as the pan leg doesn't ride up my boot while riding.
Zipper runs from knee down with velcro flap. Easy to pull over pants without them rolling up.
Hip armor is a bit annoying, but will probably break in some and be more flexible. I have to check, but I think the knee armor can be moved up and down...
I'm pretty happy with the purchase. Paid about 115 for the pants.
Will update as I wear them more.
