Keep your young helper warm on cold days with the Carhartt Boys' Straight Fit Mid-Rise Lined Canvas Dungaree Pants with Adjustable Waist. These pants feature a midweight canvas build with a warm, flannel lining, for all-around comfort that stands up to hard play. And, the fabric has been pre-washed, so the dungarees feel broken in from the start. They've got a side utility band, multiple tool pockets, and the same triple stitching of classic Carhartt workwear, plus an adjustable waist for room to grow.
