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.

Comfortable & well-fitting, but some differences in stiffness between batches
Size: Medium, Color: Black/Deep Blue/Deep Grey/Heather Grey
I've basically been exclusively buying these since I've discovered them. Super-comfortable and maintain their shape for a long time, but I've noticed from buying it multiple times that sometimes the pouch area has stiffer texture and more support than other times (when it's loose & stretchy like the rest of it). I wish I could specify receiving the more-supported ones because they tend to produce less....how to say, knocking the boys around.

Look great, feel great
Size: Large, Color: Black
These feel great and fit well. With most briefs I tend to the trouble either keeping the front in or not having the back cover everything but these do both things and are very soft. They also look great, even on body types not in the promo picture. They are a great set of briefs and have held up so far and I got mine a little around a year ago and wear them often.

Comfortable, but run big
Size: Small, Color: Red/Orange/Yellow/Blue
I'm a small guy and I purchased size small. The underwear are not bad. Great if you're a bigger guy or if you have a really big butt. If you're on the smaller side or skinnier though they'll fit a little loose. My butt is pretty big, but it doesn't fill out the back completely. Very comfortable though and the waist fits fine. Just a big backside. They don't ride up and so far they're durable. No fading in color and the material holds strong after many wears and washes.
