Maximum Comfort. Everyday Performance.

This 4-pack of Apex Briefs gives you our most advanced design in four core colors: Grey, Black, White, and Navy. Each pair is made with 94% Micro Modal Air® and 6% Elastane for a barely-there feel that stays cool, dry, and comfortable all day.

A soft, fabric-wrapped stretch waistband adds all-day comfort with no digging or rolling. The ergonomic pouch provides natural support and lift, with zero compression.

Ideal for everyday wear, travel, or training—this 4-pack keeps your drawer stocked with comfort and performance.

Why It Costs More – And Why It's Worth It

• Fabric You Can’t Fake
  Made with the finest Micro Modal Air — 10x softer than cotton, lighter than air, and built to breathe. Smoother than silk. Stronger than it looks.
• Tailored, Not Just Sewn
  Engineered for a sculpted, second-skin fit. No bunching. No sagging. No stretching out.
• Feel the Difference
  The moment you put them on, you’ll get it. Not just another pair—the pair you always reach for.
  
• Worth Every Cent
  Premium fabric, perfect fit, built to last. Buy better, not more.
• One That Outlasts Four
  Designed to endure. One pair lasts as long as 3–4 cheap ones—less waste, more value.
