No butt&knee fleece - confirmed
These pants have no fleece mentioned in description. I asked Burton and finally got the answer "There is a print failure on the webpage as well as on the labels" - Burton says.
So if you're planning to ride in cold weather conditions prepare yourselves to wear something extra-extra. (knees are feezing when you're sitting on a chair lift even with extra layer)
I'd say these pants are for pretty warm conditions somewhere around 20f/-6C to 30f/0C WITH extra layer.
Not recommended because i bought these right before the trip and I had no time to return/change order.
