Orca OR-270

Even though the materials used are very good. There are issues with that bag and a mixpre-3 (mixpre-6 would be the same I guess).
First the bag is really too deep for the MixPre. It's simply not the right size. The mixer slips down too far. The side flaps, when opened, cannot be fixed to anything, and just "float around" like big dog ears.
But the worst is the metallic zippers. When walking around they make a constant "cling-cling" sound that can ruin takes. Seeing the reputation of Orca Bags this was a real shocker. But this is a honest review.

The only thing to point out is the noisy zipper pull used, but after replacing them, it does its job pretty well. I use it with my Sound Devices MixPre 6 II.

The Orca OR-270 is a great bag for my Sound Devices MixPre-6 II! It even fits 2x SupraCell Sony NP-F970 batteries, which I was unsure about—I was afraid they wouldn’t fit, but they do perfectly!

I think that when some previous reviews mentioned too much empty space in the bag, the solution is to secure the MixPre-6 II with the included straps. The best way to do this probably requires some experimentation.

There is enough space, and the side pockets can be easily opened during recording when cables are connected. Overall, I’m happy with this bag!
