First off, i'd like to commiserate with anyone shopping for these pants, you likely also have a rambunctious 7/8 year old boy who wears out his school uniform pants on a regular basis as well.

On first glance i thought these had a lot of potential, the material seems more durable than the other brands of school pants that i've purchased in the past. My son even commented on how fancy they looked, i think he liked the rear pockets... however:
- Size 7 is probably more like a size 8, at least in the waist. Even after tightening the inner elastic bands to their tightest notch, My son still complained about the pants being too loose. (I have another brand where size 8 tightens just fine, though they are a bit on the long side.)
- There are two external straps ("Adjustable Tabs") that are there to tighten the pants around the waist. Certainly they were less than worthless on my son, who is a solid size seven in at least two other brands. They don't tighten very far at all, and even when they do, they don't hold tension and come undone right away. Essentially they'll just get in the way of a belt, and i'll probably cut them off if/when we use one. If they could hold tension, i could see them in place of a belt, but as it is, they're worthless.

Bottom line: These pants may be worthwhile once i find his belt, but the sizing seems closer to "Hefty" (length is OK, waist is too large) with very little adjustability. My son is about 4'4" and 54 pounds.
