Currently pregnant with my 4th child and I used Lansinoh disposable nursing pads through my first 3 pregnancies and opted to finally go with washable. The bag it comes in has a very silky feel to it. It isn't stiff even with the waterproof film on the inside. The bag is big enough to hold all the pads with a little extra room so you aren't trying to shove 8 pads into a Baggie. It has a small handle with a snap to ensure you don't loose it In a Diaper bag, purse, or pump bag.
The pads we very silky. One side has a terry cloth like feel and the waterproof side is silky as well. There is the slightest crease sewn into them to allow them to form to the breast but it's not enough to come out (especially when you are engorged!). In the upper left corner of my picture I have placed a pad over the disposable Lansinoh on to show a size difference - it's the same size as the inner pad and slightly smaller if going by the outer rim of a Lansinoh pad.
I have yet to leak heavily into these (thus my 4/5 stars) so I do not know about capacity of liquid but I'm comfortable and confident with these and will definitely buy them again. Would love to have an option to buy the bag separately so I can have them in different places but I guess I'll have to order them again, which is fine by me!
Update: I would suggest washing these first just to get the small amount of fuzz off. They hold a good amount of leakage- I have yet to leak through. They hold their shape great after washing and even with them being relatively flat the lay perfectly under clothes. They are amazing and would buy these again !!
