Haunted Mansion Sleep Pants Sz S

Haunted Mansion Sleep Pants. Purchased at the parks 3 years ago. My son got them and wore them but I can't remember if they were unisex or mens. They have pockets and a draw string. It does look like the seam is pulling under the button line on the front but you have to pull it to see that it is stretching. Inseam is 29" and out is almost 38".
