These are an extremely comfortable pair of leggings.  They are stretchy and soft.  I'm tall (6') and found them to be long enough to come to my ankle, as shown on the model.  However, the waistband and upper area stretch out something fierce.  I have a 28" waist and usually wear 28 or sometimes 29 in ladies pants, and these pulled up and zipped easily, but after a few hours of wear fell down so much that they sagged in the crotch.  I'd get them like 3 sizes down.

I thought that they might be jeans (they say "jeans), but they are definitely not.  The fabric is absolutely a legging fabric, I doubt they will hold up very long - but they're comfy, for sure!
