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 Certified Organic Cotton (exclusive of waistband & trims)

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!

"As soon as I switched to these, I threw out all my old polyester underwear. If you care about your testosterone, these are a no-brainer."

Greg M - Verified Buyer

Here's your old polyester boxers...

... versus your new PRIMALS 100% Organic Cotton Boxers

You've got questions. We've got answers.

What's so bad about modern underwear?

Well where do we start? The problem is standard underwears are:

  • Made with polyester & elastane
  • Contain toxic dyes
  • BPA & microplastics
  • PFAS & formaldehyde
  • Sprayed with pesticides
  • Constrict your package
  • Erectile dysfunction & shrinkage
  • Reduce testosterone & fertility

The toxic, endocrine disrupting and carcinogenic compounds used to produce modern underwear are absorbed through the sensitive areas that they cover. This is even more so the case when heat is applied like when you are exercising or are in the sauna. The key to never absorb such compounds is to wear all natural fabrics especially when it comes to underwear.

Here are some references:

What are PRIMALS Organic Cotton Boxers made of?

Our PRIMALS Organic Cotton Boxers are made of:

  • 100% GOTS Certified Organic Cotton
  • 100% Non-Toxic Dyes

What are the benefits?

People who made the switch to PRIMALS Organic Cotton Boxers are already experiencing:

  • Improved blood flow & package function
  • Increased comfort with moisture wicking and cooling effect thanks to cotton's natural properties
  • Reduced chronic disease risk
  • Restored hormone health
  • Improved reproductive health
  • Improved fertility
  • Increased testosterone levels
  • Boosted masculinity & confidence

Here are some references:

What's different about ours?

Now that you understand the sheer importance of wearing natural, organic fibers particularly when it comes to underwear. What makes PRIMALS Organic Cotton Boxers the best?

While other "organic cotton" boxers on the market seem to be decent options - the issue is that the majority of them are not truly 100% organic cotton. Many of these leading brands contain 5% elastane for the sake of marginal improvements in stretch. But the good news is PRIMALS Organic Cotton Boxers are designed to have that same functionality and flexibility while staying 100% organic cotton.

The fact is, if you take your long term physical, hormonal and reproductive health seriously - you cannot afford to settle for anything less than truly 100% organic cotton boxers. Our boxers are designed for maximum comfort and function while also using the cleanest materials possible. It's simply the best mens underwear on the planet.

So get yourself a pair, and you'll see exactly what we're talking about!

How do I pick my perfect size?

By Waist Size:

Small: 29-31 inches

Medium: 32-34 inches

Large: 35-38 inches

XLarge: 39-43 inches

XXLarge: 44-48 inches

When unsure about which size to choose, we typically recommend you select a size that's 1 size higher than you usually wear for a loose and 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 they will slightly shrink to your perfect size!

What you're wearing is harming your health

Polyester Boxers Are Made From Plastic and Toxic Chemicals.

Most boxers today are made from polyester-a synthetic fabric produced by melting down plastic bottles, packaging, and industrial waste. What’s worse, it's not just bad for the planet-it’s silently harming your body. A PubMed study proves that polyester fabric releases toxic compounds like microplastics, BPA, and phthalates. These aren’t trace amounts-they’re absorbed by your skin with every wear. You’re not just wearing fabric. You’re wrapping your manhood in plastic and hormone-disrupting chemicals.

This isn’t just skin-deep

Heat, Sweat, and Friction Turn Polyester Into a Health Threat.

Wearing polyester boxers during intense activity-like working out or in a sauna-turns up the heat, literally. This heat speeds up chemical release from polyester, allowing BPA, phthalates, and microplastics to break away from the fibers and seep into your skin. The groin area is one of the most absorbent parts of the male body. And when it’s sweating, compressed, and rubbing against heated plastic fabric? It becomes a fast lane for these toxins to enter your system. Worse, polyester traps heat and moisture, turning your underwear into a toxic, hormone-disrupting oven.

It’s not just discomfort-it’s destruction

Toxic Fabrics Lower Testosterone and Damage Fertility.


Research from PubMed shows that the very same chemicals released by polyester-BPA, phthalates, and microplastics-are powerful endocrine disruptors. They enter your body and wreak havoc on your hormonal system, lowering testosterone, harming sperm quality, and disrupting your natural balance. Your underwear might feel normal, but beneath the surface, it’s weakening your reproductive health, messing with your hormones, and draining your strength. You’re not just being exposed-you’re being attacked daily.

No plastics. No compromises.

PRIMALS 100% Organic Cotton Boxers Shield Your Manhood.


PRIMALS boxers are made from 100% certified organic cotton-no plastic, no synthetics, no chemicals. Just clean, breathable fabric that respects your body. They don’t leach toxins.

Best Boxers and Customer Service

These are the best boxers I have ever worn. And typically I hated boxers compared to underwear, but Primals converted me to boxers. They are an incredible material and are so comfortable. Plus, the customer service is literally some of the best I have ever interacted with. There was an error on my original order on that I only got half of my order, but as soon as I reached out they were beyond fast in helping resolve the issue. I cannot recommend Primals in general and the boxers specifically more!

Ethical choice that feels better too

I bought these for the organic cotton and low-waste packaging turns out they’re also the most comfortable underwear I own. The waistband doesn’t pinch, the seams don’t irritate, and they’re perfect for everything from work to sleep.

Best investment in everyday comfort

I didn’t expect boxers to make such a difference, but these are on another level. Soft, breathable, and they don’t ride up. Plus, they hold up well in the wash still feel brand new after weeks of wear.

J
Jaron Gaines
A Staple in my sustainable wardrobe

Everything about these boxers just feels right fit, fabric, and the fact they’re made ethically. Great for everyday wear or lounging. They’re the kind of basics you want to own more of.

Comfort that lasts all day

These boxers hold up all day with zero adjustment. The waistband is snug but not tight, and the fabric stays cool even during workouts. They’ve replaced all my synthetic pairs.
