Don’t think the video specifies, but they switched in 2021. The way you can tell is that the material actually got better when they switched. The only reason they were still using ePTFE at that point was for brand reasons.

The real trick (and what the video doesn’t mention) when buying waterproof garments is to only buy 3 layer construction, and then use your own insulating layers. 3 layer means the inner layer is bonded to the membrane which makes it both far more durable and lighter weight than 2 or 2.5 layer construction. Especially never buy anything 2.5 layer, they’re the worst of all worlds: generally the least durable, least breathable, and most likely to clog up the pores.
