Solid Boxers

Brandon Ko

The overall quality of these boxers is very good. The waistband is a very soft material that also feels durable. The boxers hug my body tightly but not uncomfortably.

Amazing Briefs

Brandon

The overall quality of these briefs is very good. The waistband is a very soft material that also feels durable. The modal blend is quite comfortable as well, and doesn't hug my body too tightly. Not sure why the fly is pointed upward (doesn't seem to make a difference), but it doesn't bother me.
