The Men's Kinetic Boxers are built for high performance & high output endurance activities. Made with a moisture wicking four-way stretch mesh fabric & grip elastic leg opening for excellent aerobic comfort. Every pair of Saxx underwear houses their patented Ball Park Pouch construction. Designed for contact-free support, this 3D hammock-shaped pouch keeps everything in place, thanks to mesh panels that prevent skin-against-skin friction, & no exposed stitching for no-chafe comfort. Taking a 360-degree view of the body, Saxx consider fit, feel & function, & use nine panels of fabric to create three-dimenbsional shaping around your glutes, thighs, quads & hamstrings, including the built-in mesh panels of the Ball Park Pouch. Flat Out Seams provide smooth, against-the-skin contact. & while most underwear companies place the raised-thread seam against the body, Saxx have reversed conventional thinking & placed the flatter, softer side of the seam inward, for chafe-free comfort.
