Yeah, pants are pretty key pieces of equipment really, even things like kneeling behind bunkers are so much more comfortable, regardless of whether or not you're sliding about!
i bought angel a- cam's from just paintball last year , played woodsball about a dozen times still good as new . although still wear my army combats if its really hot
i have had my paintball pants for over a year and they are still ok.... a few burn holes in the knees from indoor training but apart from that they are all good
