Full details

Crafted with a lightweight, quick-drying polyester fabric and a comfortable, regular fit, these trunks transition seamlessly from the water to casual settings. While the integration of a brief liner provides security during high-intensity movement, potential buyers should note the 4.5-inch inseam length, which offers a shorter, more athletic cut compared to standard boardshorts.

  • Sustainable design using bluesign® approved, recycled materials
  • Regular fit offers a balance of comfort and style

Setup, Compatibility & Care

Getting the right fit starts with the elastic drawstring waistband; tie it firmly before jumping into rougher surf to prevent the shorts from shifting. Regarding care, always rinse your trunks thoroughly with fresh water immediately after exposure to chlorine or salt to prevent fabric degradation. Machine wash on a gentle cycle with similar colors, and avoid using harsh bleach or fabric softeners. To maintain the elasticity of the waistband and the longevity of the synthetic fibers, it is recommended to air dry the trunks away from direct, harsh sunlight.
