These pants are pretty nice but I do wish the denim and fleece was a little thicker and because I have an 8 year old boy that is hard on pant and usually puts holes in them before growing out of them. I would have returned them, but I bought them to replace his favorite pair of fleece lined jeans that he did grow out of, which did have thick denim and fleece which did make them very durable and warm, The benefit of this pair is that he can wear them more often due to them being thinner.I guess I'd consider the fleece lining on these 25% function, 25% comfort, and 50% fashion.El producto es bueno el problema es la talla mi hijo tiene siete años y adquiri la talla 8 y a un a si le queda ajustadoGreat quality jeans, they have tightening inner belt which came in great since my boy is rail thin.I purchased for my grandson for Xmas so I won't know how they are till after that.Boys lined pants are hard to find. The quality and service were excellent!Quality was great....just too expensive for something my kids gonna outgrow in a couple (or less) months....decide to return.
