Sizing Chart

By Waist Size:

Small: 29-31 inches

Medium: 32-34 inches

Large: 35-38 inches

XLarge: 39-43 inches

XXLarge: 44-48 inches

We recommend sizing up a size for a looser, airy feel! That way, if the boxers are slightly bigger than you prefer, you can simply wash & dry them on a high heat setting and the boxers will slightly shrink to your perfect size.

Materials & Product Care

100% GOTS and OEKO-TEX Certified Organic Cotton (exclusive of waistband and trim)

PRIMALS Boxers are never superwashed - so you get truly natural fibers the way nature intended, without hidden chemical & polymer coatings sitting against your skin, unlike other underwear brands.

While cotton garment shrinkage is usually minimal (less than 5%), we recommend washing your PRIMALS Boxers with cold water and tumble drying on a low heat setting to minimize any possible shrinkage.

Real organic cotton, certified

GOTS and OEKO-TEX certified, so I know it's legit. No sketchy dyes sitting against my skin all day.

OWEN S.

No plastic in the fabric

Zero elastane in the body, just pure organic cotton. My skin's happier and I feel better about the switch.

LEVI H.

Cleanest pair I've bought

Non-toxic dyes, organic cotton, no synthetic blend. It's rare to find basics this clean. Worth it.

NOAH W.

Softest boxers I own

The organic cotton is unbelievably soft right out of the pack. Breathable too, no sweaty, stuffy feeling anymore.

WYATT P.

Finally breathable down there

My old synthetic pairs trapped heat all day. These actually let my skin breathe, huge difference in summer.

ROMAN K.

Soft and gets softer

Already soft on day one, and they've only gotten softer with each wash. I've basically replaced my whole drawer.

AUSTIN B.

Relaxed fit I can live in

Roomy without being baggy. No bunching, no digging waistband, just comfortable all day, even lounging.

HENRY D.

No riding up, no squeeze

The cut sits right and stays put. Comfortable enough that I forget I'm wearing them.

MASON R.

Comfiest everyday pair

These became my go-to the day they arrived. Easy, relaxed, and the waistband doesn't dig in at all.

CARTER L.

Nothing coated on the fabric

Love that they're never superwashed, so there's no chemical finish against my skin. Just clean cotton.

ELI C.

No weird coating feeling

Some cotton feels oddly slick from coatings. These feel like real, untreated cotton, exactly what I wanted.

GRAHAM T.

Raw, honest cotton

No polymer coating, no superwash, nothing sprayed on. Just organic cotton the way it should be.

JONAH F.

The problem

WHAT YOU'RE WEARING IS HARMING YOUR HEALTH

POLYESTER BOXERS ARE MADE FROM PLASTIC AND TOXIC CHEMICALS 

Most boxers are made from melted industrial plastic waste. A PubMed study proves polyester fabric releases microplastics, BPA, and phthalates directly into your skin. You are wrapping your manhood in hormone-disrupting toxins with every single wear.

  • Made from melted industrial plastic waste
  • Releases toxic microplastics into your skin
  • Leaches hormone disrupting chemical compounds
  • Absorbed continuously with every single wear

The mechanism

THIS ISN’T JUST SKIN-DEEP

HEAT, SWEAT, AND FRICTION TURN POLYESTER INTO A HEALTH THREAT 

Sweating and body heat melt synthetic toxins right out of heated polyester fibers, creating a direct fast lane through highly absorbent groin skin and straight into your system.

  • Heat accelerates the leaching of toxins
  • Absorbent groin skin absorbs chemicals fast
  • Sweat and friction bypass your skin barrier
  • Trapped moisture creates a hormonal hazard

The effects

IT’S NOT JUST DISCOMFORT—IT’S DESTRUCTION

TOXIC FABRICS LOWER TESTOSTERONE AND DAMAGE FERTILITY 

Research shows that absorbed microplastics, BPA, and phthalates act as powerful endocrine disruptors that directly lower testosterone, damage sperm quality, and sabotage your daily hormonal health.

  • Directly lowers your testosterone production
  • Degrades sperm quality and reproductive health
  • Disrupts your natural endocrine balance
  • Drains your physical strength and masculinity
