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.

Good underwear. Husband likes them.

Color: Black, Size: Large

Husband wears XL and XL fit well. This is the second pack I got for him. They are decent quality, look and feel nice, not baggy yet not too tight anywhere. They are somewhat thin (but still supportive) and do not make him sweat more so he loves that. No problems washing (they didn’t shrink). Will continue to repurchase these.

Comfortable

Color: Black,navy,burgundy,brown, Size: Medium

I have had a lifetime of different briefs, some name brand, some generic. I am 165 lbs, wear Medium, and these are closest to feeling commando of anything I’ve ever worn. Comfortable, not too tight waist and legs, and yes silky touch yet not slinky. Maybe not for support wear, but casual and cool comfort, the “Cat’s meow”. I just came on to order some more
