I used 2 separate bags of delicates, only filling each bag 1/2 full to give the items inside room to agitate. I used one of the smaller round ones and inserted 2 sports bras, each turned inside out. They were then put in the washing machine with some towels and a few loose garments on Gentle cycle, cold wash. When removed from the machine the bags were quite beat up and appeared dingy, still a little dirty, like the clothes inside, they needed a second washing. In the picture below the lower bag on the left came out of its first use looking damaged, the other two bags had not gone through a wash cycle yet.
