Hello, can you help me, here?

Does anyone know who are they? I found this on tumblr, however, it was tagged as "unknown" and it seems that nobody knows where this is from. The label is visible (shorts of the first guy) but I don't know which brand it is too.

Thanks a lot!

I found another pic but not their names.

One is found.
