First off, these jeans are super soft, even luxurious. That being said, I can't get these to stay at my waist because my scrawny thighs seem to exert some downward pull on these jeans...perhaps they're too flexible? I've been a loyal fan of the flannel-lined original mountain pant and generally try to buy myself a new pair each year, but these were on sale so I thought I'd try them. There's no comparison. They are nowhere near as warm as the lined original mountain pant and they just don't feel like they're going to be as durable.
