My absolute favorite boxers ever
Size: XX-Large, Color: White
I'm not a man, but I'm a nonbinary person with a big bottom and have tried many quality boxer brands over the years (including the unisex brands). These are my absolute favorite brand of boxers. They're super comfortable. It's taking me a while because I just keep forgetting to stock up but they are replacing all of my other boxers.

Good fitting support !
Size: Medium, Color: White
Just what the man needed. Very good contoured support. No jostling. Not a loose potato sack after an hour of wearing this. Highly recommended. Compare? Hanes, for example. Even the Jockey brand. Put those on, they're tight fitting, seemingly supportive. But they're not. They aren't contoured to fit. That's the whole idea. Contoured, to fit. And stay fitted. The trunk type, just like this wirarpa, and in half an hour it's loose loose loose fitting. A potato sack. No support. No support at all. That's not what a trunk brief is supposed to do. It's supposed to support, give comfort and confidence, stay in place feeling. Assuredness. And this wirarpa Mens Trunk does the job ! Wash and wear and wash and wear. Stays in shape, never gets stretched out and loose, for the fit.
