It may be that Athabasca is rebranding the Nisi filters. I have not seen or heard of Athabasca before. I tested a bunch of filters with a spectrophotometer, which is what I used to determine the neutrality of the filters. The round 105mm Lee polarizer and the Nisi filter were neutrals as were the Breakthrough Photography round filters. The Lee square polarizer was not neutral. The 10 stop Lee filter I own is not neutral at all while the Nisi was very neutral, no color cast.

I owe 77m X4 Breakthrough polarizer, and ND, I see know color cast at all, but their 100mm holder doesn't have ability to rotate polarizer, like Nisi design, otherwise I would go for it. They're not cheap, but they're excellent.
