Not sure if use of recycled materials is responsible, but I bought a new Patagonia R1 fleece pullover a few years ago and it was utter garbage compared to its 20-year old predecessor (technically, same model). Probably the worst-fitting item of clothing I own, and the fabric is incredibly uncomfortable. Meanwhile, chest zipper on the original has gone out, but it fits as well and is just as comfy as the day I bought it.
