I'm 8'8 tall, ordered a size L and they fit great. Very comfortable in cool weather this spring. The cuff zippers help with the onoff.
I have a 32 inseam and weigh 170 lbs, barely got the things on they were too tight.
Gave them to the wife who is 40 lbs less same height, damn things wouldn't stay on.
They worked to keep out the chill, but actually cut into my thighs during the ride.
Caveat emptor indeed
