This pouch holds three filters up to 77mm with great protection. I like it because it is as small as possible and still able to do the job. I use it in my camera bag so I can easily retrieve my three filters. I have one pola filter and two UV filters for my two 67 mm lenses. I just got it so I can't say how well it will hold up after repeated uses. In other words, how long will the mesh pockets last.
