Much thicker than you think. Nice bags. But super sloppy packaging. They taped them in a loose flimsy bag and they were everywhere when I opened the package. I was picking up bags for 10 minutes. They are slippery and they roll them up. A box or a heavy bag to hold them would have worked great. When I say the bag they put them in was flimsy I mean like your fingers touch will rip the bag, that thin. But as for the bags, perfect. I can pack my customers clothing in them without worry. I will buy from again, I will just be careful when opening.
