These are NOT lined with anything, and burned my hands when I used them to pick up a cookie sheet. They do not protect from heat whatsoever. Very disappointed as they were to match all my other orange utensils. Not idea what that 5 star review is going on about; that person is insane!

Definitely keeps heat out for several minutes and wipes clean. I never felt heat, just warmth after a few minutes. Bought 2 more to give as gifts.

According to the reviews these silicone gloves are supposed to be cotton lined.They're NOT lined!!!! False reviews!
