Undergear Men's Open Back Trunk

Soft, smooth stretch and a distinctive open-back cut give this Undergear trunk a comfortable feel with a refined, expressive edge. Designed for confident everyday wear, it pairs a supportive contour pouch with a lightweight profile and a clean finish.

• Fabric: A smooth blend of 80% nylon and 20% spandex offers comfortable stretch and a soft feel against the skin.
• Fit: Regular fit with a 1.5-inch inseam, a contour pouch and an open-back style designed for freedom of movement and support.
• Waistband: Covered elastic sits securely and comfortably, while the lightweight construction keeps the feel easy to wear.
• Craftsmanship: Dye-to-match thread and self-fabric piping at the leg openings create a coordinated, polished finish.
• Color and care: Available in Red/White and Purple/White, in sizes S through XL. Machine wash cold on a delicate cycle; tumble dry low. Use only non-chlorine bleach and cool iron if needed.

Part of Undergear’s modern approach to men’s trunk underwear, this backless design balances practical comfort with a subtle, sensual silhouette. Choose your color and size for a considered addition to your underwear rotation.
