At the risk of making myself unpopular, I will say that in some situations I prefer pants/shorts. The more casual the activity the more I would favor bifurcation. I grew up in farm country, and there's just no competiting with good carhartts for protection and durability. I find kilts too exposing in rough and tumble situations. (Probably why you don't see them in combat anymore.) I tried being outdoorsy in kilts and just too often found myself thinking pants would be a lot easier.

However, as a rower and runner and owner of beefy quads, I will say I love the openness of the kilt in many respects. Often at work I wish I was kilted bc trousers tend to kill my Hardy boys, and that's no mystery.
