This is heavy duty.
It was big enough.  Almost too big.  I thought I was getting 3 of these for the price, so I was surprised to only get one.  That was on me, I had been shopping three packs when I saw this one, and thought I was still shopping 3 packs.  It is quite heavy duty, but I found it so thick that it was hot and hard to breathe in.  It is absolutely what it is described to be, I just don't need that much and don't want to spend that much.
