This bag is small enough to always have it. But is spacious enough to hold even Cokin P filter. I have four of them (naked, without box) plugged in, plus two adapter rings (58 and 72 mm). Also, the filter holder fits into it somehow. It would be better, however, when a tray (for example, the rearmost) would be slightly wider to accommodate thicker things or flat boxes. The Cokin lens hood is too big for this bag, but I use it anyway very rare. For pole-filter and UV filter still there place.
