not sure i would work in these but I love these cycling pants. they aren't tights. they are form fitting but not not tight. they are made for cycling and flattering. they stretch where they are supposed to and dignified while walking upright. like I said you might want to store some work pants because these do look like cycling pants. I wear my cyclign shorts or cycling liner under while riding but you can wear any underwear, of course. they have a nice thick spongy feel.
