Are the these pants light wieght material, and do they last long?
They look like a fairly lightweight material. Can't say for sure. Definitely a 2L, so I wouldn't expect too much padding or thickness to them. As for lasting, like any clothing, if you are gonna put these through serious abuse, they are gonna break down no doubt.
For reals though, right now, these things are 40% off, and according to some previous reviewers, that price drop is significant enough to warrant you copping a pair of these and shredding the hell out of them!
