That looks awesome, a bit big but its nice that it even holds the holder in it as well.

This is something that had to have been solved already. I imagine a hard case along with placing soft tissue or foam in between each filter so that they're all nestled.
That could work, but it would also mean there are a bunch of loose lightweight floppy things on those windy days or just bad weather in general. If one of them flies away its now filter against filter.

does the lee filter pounch/holder/case not work then?
I honestly don't know. I had my tripod all setup one day out in the bush and a random photog let me hand hold a filter he had for his film camera and we started chatting. He said he used the pouch (I think it was) for all his Lee filters and after a day of hiking and bouncing ever so slightly back and form in the pack he had his filters all scratched up. So he changed into a hard case to carry them and never had a problem with his new (replaced) filters and figured he would pass on the message as I told him I was planning to get filters down the road.

This Lowepro filter pouch is made for 10 4x6" filters and a filter holder too, with room to spare. If you are only using 4x4" square filters or 4x5" Hitechs, its an overkill. Heck, it seems overly large to me and I have 4x6 filters as well as both a P and Z size filter holder. It is rather thick, I wish it were a bit thinner.
Before I was using a very thin f64 pouch for 4x4 and P size filters.

The Lee filter pouches that come with the filters are impressively robust and fine if you only had one filter. If you had several, they will really take up a lot of space.
Thats good to know Mike thanks. I will most likely be carrying 4 filters that are 4x4 and 4x5. Possibly a 4x6 and the holder since I generally bring a small ICU from F-Stop for the lenses and camera and it does not fit the holder on the end of the lens the way I have it setup. That or a bring the medium size and I lack gear space.
I wonder if they have a smaller version of that pouch.
