I've had great luck finding husky jeans at Sears, JC Penney and Wal-Mart (much as I dislike Wal-Mart!)
Sears has a brand called Canyon River Blues and my son always liked them more than the "name brands" because they are really soft/broken in feeling. Now that he is 12...I can buy pants by waist/length...which is such a relief!
My sons are total opposites (the oldest is a husky, the younger is a slim) so my younger son will never be able to wear his brothers hand-me-downs. I give all of my younger sons old clothes to my girlfriend, ( her son is a slim also). I have never had anyone to pass the husky's down to. I keep all my outgrown/seasonal kid clothes in storage bins and go through them in the spring and fall to rotate their dressers. If I have some old husky jeans...I would be glad to give them to you. You can email me at ____@____.com if you are interested.
Good luck...
