Nobody from Team USA is leaving the Tokyo Games empty-handed ... 'cause athletes are getting hooked up with a TON of free stuff -- from kicks to threads to phones!!
USA weightlifter Mattie Rogers gave fans a sneak peak of the team's awesome swag bags all the way from Japan ... showing off all the fun new gifts everyone got for making it to the big stage.
Naturally, there are a bunch of bags filled in her room ... so Rogers starts things off with some bright pink Nikes all the way down to USA-themed kicks.
