The Merz b. Schwanen Underpants might just be the perfect pair of boxers. Why? For starters, they're knit on a loopwheeler machine using 2-thread yarn. This results in a fabric that is slightly heavier than what you'd expect from typical underwear fabric. This means the underpants will keep their shape all day long and won't ride up. They're incredibly soft and supportive without being constricting. And the smooth cotton knit ensures they'll breath well all day long and won't bunch up under your favorite pair of jeans.
