I've been searching for the past month or so for a pair of hard shell pants for backpacking and general mountaineering. I checked out the Patagonia Triolet, Mammut Convey, Outdoor Research Paladin and the MH Quasar. I ultimately decided on the Outdoor Research Paladin. I felt like they have the best combination of features, durability and weight.
I liked how lightweight the Quasar were, but I thought the inner gaiter was worthless. No pockets didn't seem practical. The 15D material did not inspire confidence with respect to durability. Most importantly to me, the fact that you can't vent the pants using the full side zips (without them falling down), seemed like a bad design to save 1 or 2 ounces of weight. Perhaps, the DryQ material is so breathable that you don't even need to vent, but I didn't have a chance to test.
