Sponge for Travel Wash Rag

I use this type of sponge for cleaning my body when traveling. I wrings out good and does not mildew in bag.

A wash rag in your bag will MILDEW - It will stink, you need something that you can squeeze all the water out of, a sponge is the solution.
 

I take a normal sponge in the store, I rip off the abrasive part, not needed, just  an option.
 

There are various textures, you can choose.

I often will cut a hole in the end, then slide the soap inside for protection inside my bag.
Nothing worst than to have a loose bar of soap in your bag, makes the toothbrush taste bad.
