Loose pants, tight boxers: Why our underwear is stuck in 2010

Thank God we left the 2010s behind us. I don't miss the era of skinny jeans for a second—a time when we had to squeeze ourselves into trousers every morning that cut off the circulation in our legs. Restricted range of motion, sweaty legs, underwear riding up. Luckily, in the 2020s, we are back to wearing loose, comfortable trousers. Cheers to freedom for your legs!

But wait a minute, what is actually going on underneath?

It’s completely absurd: While most men fancy themselves in newfound breeziness in wide-cut Levi's jeans, the boxers underneath are stuck in 2010. Tight boxer shorts made of cheap fabrics from the well-known brand with the C and K or the nearest fast-fashion chain. Between "health-maxxing" and self-optimization, it seems almost grotesque how little thought we give to the garment we wear directly against our soft parts 24/7.

We see two main problems for our health with tight, off-the-shelf boxer shorts that are being ignored by the industry.

Problem 1: Tight cuts strain fertility

Let’s talk biology for a second. Your testicles don't hang outside your torso for no reason; they need a temperature that is consistently a few degrees below core body temperature to function optimally. Tight boxer shorts press everything together and block air circulation. The result: heat accumulation in the testicles, acting like a seat heater that’s permanently switched on.

Male fertility is declining worldwide, and studies suggest that the tightness of boxer shorts could be one factor among several influencing sperm quality (see here). A tight fit means: no ventilation, no range of motion, and that every day, 24 hours a day.

Problem 2: Cheap material burdens the skin and body

But even if the cut is right, a second problem remains: the fabric itself. Most mainstream boxer shorts consist of chemically treated cotton, sweaty polyester, or cheap viscose. These materials not only trap heat and moisture instead of wicking them away, but they are also often extensively treated during production with chemicals like plasticizers, formaldehyde, or even PFAS. Some of these chemicals are known as endocrine disruptors, meaning they can interfere with the male hormonal balance. And all of this is in constant contact with the part of the body that not only houses your reproductive organs but also has extremely thin and sensitive skin.

The solution: Loose boxer shorts made from TENCEL™ Lyocell

That is why we need a holistically reimagined pair of boxer shorts, and that is exactly where the loose-fitting TENCEL™ Lyocell boxers from oseas come in:

• Loose, not baggy: Wide cuts for a free and airy feel, double-stitched at common stress points, without looking baggy.
• Heat dissipation: Made of 95% TENCEL™ Lyocell—a fabric that naturally cools, further supporting temperature regulation.
• Minimal pollutant exposure: TENCEL™ production requires no toxic chemicals that could enter your organism through the thin skin.
  

So why haven't the big mainstream brands long since started producing their underwear out of this miracle material? The answer is probably as simple as it is frustrating: it's not worth it. Genuine, high-quality Lyocell is relatively expensive to purchase and lowers the profit margin. It’s likely not lucrative enough for mass production. It’s better to mix cheap cotton with elastane, slap a huge logo on the waistband, and sell it to you as "premium."

Not with us.

We at oseas have made it our mission to develop healthy, durable, and environmentally friendly boxer shorts that we want to wear ourselves. No heat buildup, no plastic against the skin, no "grandpa look." Just the best for our balls.
