Key Highlights
- That’s why details matter — the fit, the feel, how it moves with you at the gym, and how it sits when you’re hunched over at your desk.
- Our Men’s Health team is no stranger to Mack Weldon; we’ve already crowned the brand a winner for making the best t-shirts and underwear for men.
- Our Style Editor Joseph Cheatham tested the famed Airknitx Boxer Brief, so I was curious to see whether the 18-Hour Rib Boxer Brief could measure up.
- In this case, “measuring up” would mean having a waistband that doesn’t roll when you lunge, support that keeps everything in place without intense compression, temperature regulation to prevent that swamp feeling and a feel that’s as soft as your bedsheets. I got my hands on a sample pair and wore it for about a month.
- I worked and played in the 18-Hour Rib Boxer Brief in every way imaginable: workdays, workouts, bike rides, sweaty trail runs, dinners out, the list goes on.
