PUMP! Sonic Trunk
Exceed the speed of sound in the performance-ready PUMP! Sonic Trunk.
Exceptionally strong and surprisingly soft, this nylon-elastane trunk has got it all. The low-rise cut you know and love lengthens the look of your torso and leaves little to the imagination — just the way we like it. A no-fly black cotton cup keeps your manhood cool, calm, and collected, so you can run, squat, and lunge, no sweat. (Plus, who doesn’t love some natural, flattering-looking lift?) Up top, a 45-millimeter black and charcoal waistband brings it all together. We love the look of this black full-mesh body — especially out back — and the performance-ready elastic around the legs.
Nylon is the stuff athletic-clothes dreams are made of: you want a trunk that’s as moisture-wicking and hardy as it is nice to look at. Luckily for you, this one does it all.
- Low-rise fit — sits just below your natural waistline
- Ultra-stretchy feel — nylon gets the job done
- Contoured pouch — your member is in good hands
- Elastic waistband — bold and branded
