Light but fragile
At 10oz you have no excuse to not carry these, drop the full zip version and they get even lighter. I choose these since they are easier to get on/off with mountaineering boots and crampons, or snowshoes without shredding the pants.
They don't seem to breath very well so I only wear when its raining pretty good or im trudging thru deep wet snow. Also being this lightweigh means they aren't very durable, the seat will only last a few glissades before wearing thru, if they don't tear 1st, a price you pay for lightweight.
I also had to size up one size to layer these over my regular pants.
