I believe the fabric is around 10oz (this is my personal opinion, as the manufacturer doesn't specify the fabric weight). The tag attached by the manufacturer indicates a size L, but the measurements are as shown in the size chart in the images, so it feels closer to a standard size LL (XL). Please check the details in the images. The hem of the pants appears to be narrow, but they are straight with no tapering. No stains, tears, or odors.
