The Truth About Your T (and Your Underwear)

Every man talks about boosting testosterone — but few realize it starts with what’s next to their skin.
Polyester, nylon, and synthetic fabrics trap heat and chemicals against your body. That’s bad news for your health and your hormones.

Heat and plastics can lower testosterone, mess with your body’s rhythm, and cause irritation you don’t need. Cotton, on the other hand, lets your body breathe — keeping things cool, natural, and balanced.

How Cotton Keeps Your T Levels Safe

• Breathes Naturally: Cotton regulates temperature, keeping you cooler where it counts.

• Chemical-Free: Organic cotton contains no synthetic chemicals or hormone disruptors.

• Supports Circulation: Cotton’s flexibility means no restriction, no synthetic compression.
