Very thin. These are perfect for lounging around the house if you don't mind your butt potentially showing. Theyre closer to PJ fabric vs your typical sturdy leggings-as-pants material.

Ladies, if you're like me you test leggings in the store. If I can see my fingers through the material when I stretch it then they're a no-buy for me. Im sad that these are thin. They also offer zero tummy support. I think Ill stick to buying leggings at the mall.

For reference Im 57 and about 200lbs.
Im pear shaped with a belly.
