My son likes these type of pants to lounge around the house in, so I purchased 2 pair. They have a drawstring. They are not like sweatpants so don't expect that. They are medium weight material. I think the price may have been a bit high for the quality, but overall, we are happy with the purchase.
The medium size was a.bit too big so when I picked up my order, I exchanged them for a size small. The leg length is a bit too long for being a size small so I will have to hem these pants for my son. The pants are decent quality though so I'm generally pleased.
