Womens... I have discovered kids clothing. My problem is that I'm short and fairly tiny and can fit in a kids XL or 18/20 size pants. My convertable hiking pant/shorts are kids. My inseam is only about 28" and my waist size is 31 so I can just fit in the largest kids pants I can find and since a lot of the convertable pants are zippered in the legs, you can't alterate them so I tried on some kids Columbia brand conversion pants and they fit great!
BTW, I like duofold stuff too as base layers, I have bought a bunch of them from STP... (See my coupon in the Hot deals section for free shipping, if you have more to buy from them)
