I'm 6'1" with a 36 in waist and a 32" inseam. I bought these in a medium and the
Marmot Motion Pant in large, and the fit was very close - although I found the length of these was a little better by about an inch. The lining is soft, and it's included in the front pockets.
There are vents on either leg, although I can't say I'd ever use them. The
Marmot pants are much baggier. These have a neater appearance. Also, these are a bit heavier. Between the two, I'd say this is a nicer pair, and they're a little cheaper.
