French Toast Men's Flat Front Relaxed Pants Color: gray Size: 34w x 32l

My son is currently between a 7 or 8 in regular pants but the waist bands are always bunchy. Since Wangler brand 7 slim fits him almost perfectly, I thought I would purchase a 8 slim for him to grow into during the school year. The size around him is fine but the length is too short. They fit like a 6 regular. I am new to French Toast pants so I don't know if this is a fluke or not.

These pants are mandatory for school uniform. We have to buy double knee for younger boys. A month or so into wearing the uniform and holes are worn through the knees. Everytime. We have had to use these pants for years. Then the fabric lining piece on the inside that makes the "double knee" wears off and feels like sandpaper. My son complains that they rub and scratch his knee. I do not like these pants, but we have to use them. Also wish they came in slim. All my boys are tall and slim and these pants, even with adjustable waist, are bunched at the waist and baggy though the leg. I'm never a fan of khaki pants for young boys. They stain them up first day of wear.
