The devil is in the details. No, not the red-horned guy with a pitchfork, but the team at Mack Weldon who spent over 10,000 hours creating ridiculously comfortable underwear, socks and t-shirts. To start, they developed their own fabric: super-soft 18-Hour Jersey. Next came features like a no-roll waistband, mesh cool zones and stay-put legs. The result is underwear that like you, never gives up. And yes, shopping is easy at Mack Weldon. Simple selection, volume pricing and amazing service. Not satisfied? No worries, they'll pay for it. They focused on the details, so you (and the devil) don't have to.
