They are all fake.
That would explain why i didnt like mine. I paid good money for a couple of them, and thoroughly disliked them. Including Darevie bib bought via alibaba, not aliexpress.
I own a castelli BIB & skinsuit, not a fan of the pads either.
My favourite pad by far is that kind, which you can find on Aliexpress for usually quite cheap. Essentially, it's foam only, not gel, the padding at the front is as thick as it is at the back, which is essential when riding in aero road position, i find, meaning being tilted forward a fair bit (rather than very upright). The foam is dense and it's dense at the front, which is what i want from a pad. The elastic interface, castelli, and other pads i've tried, and i've tried many, including from expensvie custom kit and so on, are softer overall and thinner at the front.
Mind you, i'm 81-84kg and do most of my riding on the flat, sitting. If you're climbing out of the saddle all the time, i find i can agree with almost any BIB.
