Printed unsigned chars as hex are too long

Lets assume I have this very simple example:

vector<unsigned char> bytes {0xFF, 0xFF, 0xFD};

for (const char & v: bytes) {
    cout << hex << setfill('0') << setw(2) << uppercase << static_cast<unsigned>(v) <<" ";
}

cout << endl;

This gives:

FFFFFFFF FFFFFFFF FFFFFFFD

However, I would like to have it short, like:

FF FF FD

So why do I get some many extra "FFFFF"?
