This are the best in men’s underwear. Modal fabric is the key.
Color: Black, Size: Small, Color: Black, Size: Small
Well I tried Hanes bikinis small and medium said to be the best seller. Maybe for a young boy but not for me an older man.
Tried numerous others and none fit like these.
The most comfortable of all I tried probably because the waistband being between mid and low and not so wide a fabric and fit the best.
The biggest thing I love about these is the pouch area being just right and the fabric is so soft. Modal is the way to go. Cotton bunches up.
Great quality and price. Can’t go wrong with these. Tried boxer briefs and trunks also and all to high waisted even when advertised as low, and the pouch area were bulkier.
Edited: The solid colors are ok for casual use only but not for sports. The ones with a fancy design are better. Bigger pouch area and a different style waist band.

Soft, true-fit briefs — great daily comfort, not ideal for workouts
Color: Black, Size: Large
I’ve been wearing these wirarpa modal briefs every day for about a month, and they’ve quickly become my go-to pair for daily wear. I previously owned the same brand’s boxer briefs for over a year, which held up better than any other brand I’ve tried, so I decided to test the brief version this time.
Fit and Comfort
The sizing was spot-on for me. The waistband is soft, not scratchy, and doesn’t dig in — it stays in place without rolling. The leg openings don’t ride up, and everything stays comfortably supported without tight seams in the wrong spots. I’d almost forgotten how briefs feel after years of wearing boxer briefs, but these reminded me why they’re still worth owning.
Fabric and Wearability
The modal material is silky and smooth to the touch. It’s perfect for everyday comfort and casual wear, but not the best choice for sports — it’s not highly moisture-wicking, so I wouldn’t use them for workouts or hot outdoor work.
Durability
After a month of daily washing, there’s no pilling, stretching, or loose stitching at all. If they hold up like my year-old wirarpa boxer briefs, I expect these to last far longer than most big-name brands.
Design Notes
These come neatly rolled in a sealed bag with no odor or chemical smell — a nice touch that shows some quality control.
Bottom Line
If you like a soft, lightweight brief that fits true to size and stays comfortable all day, these are a great value. Go for the boxer briefs if you want more coverage or plan to sweat in them, but for regular daily wear, these hit the mark perfectly.

Soft, lightweight, and comfortable
Color: Black,navy,burgundy,brown, Size: Medium
These briefs are soft, lightweight, and very comfortable for everyday wear. The modal microfiber material has a nice silky feel, and they provide plenty of room without feeling bulky. The fit is true to size, which is always a plus when ordering underwear online. Overall, a comfortable and well-made option if you want something soft and easy to wear all day.

Comfortable and soft
Color: Black, Size: Small
I purchased these in small. I have a 30-inch waist, and the small is loose on me. They are described as handmade, and to expect some variance, but there is a noticeable difference between individual items. Individually, they are well constructed, just inconsistent in size.

Just buy them
Color: Black,navy,burgundy,brown, Size: Small
Used to wear sliders all the time, figured i'd switch it up. These are super comfortable, probably the best material underwear I own. Great to just lounge around it or wear everyday. Fit is really good, I got a small and about 29-30" waist. Good bang for your buck too. I've washed them a handful of times and they hold up great, fit great and dont' shrink.
