Quick answer

The Modal Sports Brief offers silky softness and moisture wicking for all-day wear, while the Supplex Sports Brief provides durable, high-performance support for intense workouts. Your choice depends on whether you prioritize luxury feel or rugged performance.

Fabric feel and performance

The Modal Sports Brief uses luxuriously silky Modal fabric that wicks moisture from the body, making it ideal for long days or light activity. In contrast, the Supplex Sports Brief is made from high-performance Supplex fabric, a durable nylon-based material that offers excellent freedom of movement and is designed for active sportsmen who need maximum comfort support.

Support and design

Both briefs feature the Cocksox contour pouch for support and a butt hugging seamless wrap-around back. The Modal version has a Vicennial print celebrating 20 years of Cocksox, adding a subtle style detail. The Supplex version includes robust piping and a sportier look. The fit is similar, but the Supplex fabric feels more structured during high-motion activities.

Trade-offs

  • Fabric softness: Modal is silky and gentle on skin, while Supplex is a high-performance synthetic that feels more performance-oriented. Choose Modal for all-day comfort; choose Supplex for training or active sports.
  • Moisture management: Modal wicks moisture from the body, keeping you dry during light activity. Supplex fabric also wicks moisture but feels more breathable due to its weave. Both wick moisture, but Modal is more noticeable for daily wear comfort.
  • Durability and stretch: Supplex fabric is robust and offers excellent freedom of movement. Modal is more delicate but still durable for regular use. If you need rugged use, go with Supplex; if you want luxury feel, go Modal.
