Moisture-wicking and antimicrobial properties ensure you’ll stay dry and fresh, even when things start heating up. The low-profile, brushed elastic waistband stays put, so you never have to worry about adjusting and the enhanced front panel provides extra room and support where you need it most.
The fly adds functionality, so you’re always ready when the moment strikes. Flat seam technology eliminates chafing, making these briefs perfect for long days or long nights.
