Kuiu's fabric is a direct-vent fabric like eVent.
eVent is and has been available for several years.
I have several eVent products including my REI Kimtah jacket and Kayland Vertigo High boots.
eVent is a complete fabric, but the barrier itself is now licensed to be used in other company's fabrics, like DryQelite from Mountain Hardwear.
So Kuiu's Chugach jacket which cost $300 is comparable or better than Sitka, Arc'teryx, etc.. jackets that cost upwards of $500? Yet they still use better materials that cost more, and this is where the direct sale business model comes in? So if these things are true, and with the internet why would hunters ever buy sitka over KUIU?
Does anyone know what the Chugach jacket and sitka Stormfront jacket cost the companies to make?
I also emailed the video to Jason to get his take on it. He said that Toray has breath ability similar to eVent but is 4 way stretch which eVent is not. He said some other technical stuff but it went way over my head.
