Your foundation isn’t basic—it’s built for performance. The PRIME LAYER™ Boxer Briefs are engineered for men who move with purpose. Made from soft, breathable stretch fabric, these briefs offer maximum comfort and mobility without the bulk or bunch.

The no-back-seam design eliminates friction for a smooth fit that stays locked in, while the double-layered front pouch provides structured support exactly where you need it. The clean, athletic silhouette wears like a second skin—perfect under jeans, joggers, or suits.

From early grind to late-night reset, this is your go-to base layer.
No riding. No folding. No excuses.
