The bags themselves are made of fine mesh nylon, which allows them to still get cleaned, while preventing them from the other items in the wash. The zippers on the bag have anti-snag technology, so you don't have to worry about them catching on your clothes in the wash. This set comes with 3 square/rectangle laundry bags (small, medium, and large size) and 1 sphere bra laundry bag. The laundry bag has a shell case on both ends of the bag, which help maintain the shape of the bra while they wash (and it's also great to use when traveling to help protect them). I have a weird bra size, so I have to buy nicer bras that require they are stored with one cup folded on-top of the other to ensure that the bra lasts. This laundry bag supports this bra positioning and helps my bras not lose their shape when I have to wash them (see picture for example). It also helps the straps not get all twisted and turned around.
I have used all of the bags and they all work very well. I use the larger ones for my bigger/heavier sweaters, the medium one for any shirts or items that I may want to air dry (or are delicate), and the small one I use for underwear that I want to air dry. I am very pleased with the quality of these bags and how these help my clothes stay nicer, due to the ability to separate items as need be for washing or air drying. This is a simple solution to increasing the lifespan of your clothes. I am very very happy with my experience with these. You just put the items in the desired laundry bag when sorting your laundry before washing, throw the bag in the wash with the other items, and then remove it when you transfer your items to the dryer. I believe this can go in the dryer, but I exclusively use it for items that I don't want to go in the dryer. I've used these for multiple washes and the bags have been holding up very well! I'm a very happy camper!
