No clue at all what brand these boxers are, but I think they look nice! They’re a very traditional look, with a simple pattern on what appears to be a slightly stiffer, sheet-ier kind of fabric – definitely not the traditional briefs-style fabric or a super-soft, almost-formless cotton. I imagine it’s almost a little slick to the touch, in a way. The waistband also looks like it could be a little on the crinkle-y side, especially with the kind of fabric I’m thinking of.
I have a pair of boxers myself from Jockey that I think are comparable to this pair in terms of fabric, but it’s just a guess. It’s the kind of boxers you might think of for a 9-to-5 office-worker kind of stereotype. (My Jockey boxers even have a button-close pocket in back! A bit weird, but kinda fun.)
Even if the fabric is a little on the stiffer side, these boxers were apparently designed with enough of a front to give a fairly good look to the pouch here as this daddy is wearing it! He definitely seems to be providing a nice shape up front, and he looks comfortable wearing it too, which is of course always the most important part. It kinda looks like the pair has a fly, but it’s hard to tell exactly; between the angle and the lighting, I can’t see an obvious button, and the fly isn’t obviously semi-open either, which can often happen with boxers and similar things when the way you’re standing causes the two halves of the fly to fold differently.
