How Do I Know What Size To Order?

Use your waist measurement and our size chart to find your best fit. If you're between sizes, we recommend sizing up!

Will The Waistband Roll Under My Belly?

The wide StayFlat Waistband™ is designed to stay flat against your belly instead of folding, rolling, or digging in when you sit and move.

What If I Have Bigger Thighs?

That’s exactly what we accounted for. Extra room through the thighs gives your legs space to move without squeezing, bunching, or constantly creeping up.

Will They Help With Chafing?

The longer-leg design keeps more fabric between your thighs, helping reduce the skin-on-skin rubbing that can lead to chafing.

What If It Doesn't Fit?

Try them risk-free for 30 days. If you don’t love the fit, get a full refund — no questions asked, no need to send them back.

What’s The Material & How Should I Wash Them?

95% cotton and 5% spandex for soft, breathable comfort with just the right amount of stretch.

Machine wash on cold with similar colors and dry on low heat.

    "I cannot go back"

    "As a big person, I wore Hanes boxer briefs for 20+ years. Then I noticed I was adjusting them all the time and my waistband became increasingly uncomfortable through the day. On the second day wearing these, I noticed — no fidgeting with my waistband. On the 4th day, I tried one of my old pairs and immediately ordered 3 more sets of 3. I cannot go back."

    "Waistband doesn't roll"

    “Finding underwear that actually fits right without bunching up or feeling like a straitjacket is a struggle, but these briefs are the real deal. Even after a long day running errands or sitting at my desk for hours, they keep me from feeling swampy. The waistband doesn’t roll down or dig into my skin.”

    "6 Months. Still Going Strong"

    "Best Underwear I've ever owned. Had them for 6 months and there's not a single hole and they're not stretched out like most other brands. Great for big guys 350+. Thick Fabric. Durable!!!!"

Bigger underwear isn’t the same as underwear built for bigger men.

Most underwear brands start with a size medium pattern and simply make it bigger for larger sizes. The result is underwear that might fit your waist — but still fits wrong everywhere else.

That's why you've been stuck dealing with this:

  • Waistbands that roll under your belly.
  • Legs that ride up and bunch.
  • Thighs that rub and chafe.
  • Underwear you have to adjust all day.

Nobody designed underwear around how bigger men are actually built. Until now.

We rebuilt the pattern from scratch.

We call it the Proportional Fit System™ — each part is designed around how bigger men are actually built.

  • Extra room through the thighs so you can move without squeezing, bunching, or riding up.
  • Wide StayFlat Waistband™ that stays flat against your belly without rolling or digging.
  • Longer leg coverage keeps fabric between your thighs to help reduce rubbing and chafing.
  • Roomier pouch for comfortable support without squeezing or feeling cramped.

No rolling. No riding up. No constant adjusting. Just put them on and forget about them.
