With the current trend for young boys' jeans to be skin tight or fashionably ripped, these have been a godsend. They're a replacement for the jeans we bought last year that are now getting too short. The iron knee feature and more relaxed fit means it took that whole year for them to show any sign of wear. This is in comparison to a well known chain whose trendy, skinny jeans were worn out at the knees by an active 6 year old within 3 weeks! I didn't even waste time looking anywhere else this year. These are a classic fit, good length with adjustable waist (which does come up quite big without adjusting). Last year I bought a year ahead as I always do as my son's tall for his age - but they were too big so I returned them for his actual age. So I'd say true/generous on sizing.
