Very thick, a little thicker than what my needs are. just really wanted to protect my comforter on the bed from my dog's nails . This is definitely thick enough.. his nails don't punch her but because it's so thick, it lays over the side of the bed it doesn't lay flat of course and I have to roll it up. It's a little cumbersome, but it definitely works and protects my duvet. It's clear I can see right through it so when you walk in you, see a nice looking duvet without dog holes and scratches all over it.
