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

66% Nylon / 20% Elastane / 14% Cotton
