My son LOVES sweats.  These are great quality, but a little big.  The waist has a draw string but the thickness of the fabric and the draw string doesn't tighten enough to hold the pants up on my slim-jim son.  He needs a belt or hidden tighteners in jeans etc. to hold them up.  I should have ordered a size smaller than I thought we needed.  BOTTOM LINE- Great quality sweats, run larger than expected.
