They are amazing, very soft and warm. I bought them for a ski holiday because my 7.5 year old didn't have warm pants. My daughter is of average height but very thin. They fit her perfectly so I would say they are for skinny kids. Bought M-120 and L-140. 120's are perfect right now but I don't know how long they will fit in length. L'-140 is 4 inches longer but fits her waist and stomach and will be good next year. Because they are thick she can now wear an L-140, they just have extra fabric underneath. I would call them warm leggings because she wears them with shirts and they look great. FYI - I didn't know they have a cuff at the bottom which can be both a plus and a minus.
