The PUMP! Round2 Black Backless Trunk takes a classic trunk and cuts the back out. Up front it's soft black ribbed cotton with a high-definition P! patch; behind, it's all jockstrap — just leg elastics and open space. Retro sports styling with a modern, daring edge.

Key Features

  • 50 mm elastic waistband with bold PUMP! branding across the back
  • Black ribbed cotton-elastane body for a soft, flexible, body-hugging fit
  • 25 mm leg elastics for a secure, contouring hold
  • High-definition P! front patch for a clean, sporty finish
  • Backless trunk design — trunk coverage at the front, jockstrap freedom at the back

Fabric composition

96% Cotton, 4% Elastane

Why Choose the Round2 Backless Trunk?

For anyone who wants jockstrap freedom without giving up the shape of a trunk. Pair it with the matching Round2 Backless Brief or Round2 Thong to build out the set.
