Looking gor kids Taekwondo pants

Any idea where I can find these in prospect heights, park slope, brooklyn heights?

Maybe try Modell's on Fulton St. in Fulton Mall, or on Flatbush by the Atlantic Center.

Also could you ask at your kid's school where parents normally get theirs?

Try Triangle Sports, Flatbush and 5th Ave.

they specialize in kids sports and boy scout uniforms.

I saw these folks doing a youth demo at the Court St. street fair a few weekends ago:

Perhaps they might have some great suggestions.
