I haven't tested this yet. My maximum attached mass was 9kg = 22.8 pounds. It is just my guess that you could go much higher. It is tested until 25 pounds by the manufacturer though.
How does it stay attached? I don't know what to say but you can easily wear it with 20 inHg vacuum. That is a lot of power I think. Slippage doesn't occur. I can't tell you why - we would have to figure out how to measure the friction or something.
