Men’s Trunks and Underwear

Discover mens trunks that feel as good as they look. At Peter Alexander, we create premium trunks for all-day comfort, dependable support and effortless style. Whether you want a sleek everyday pair or a bold print, our mens trunks are made to move with you and stay looking fresh, wash after wash.

Why Choose Our Men’s Trunks?

Comfort begins with the fabric. Our mens trunks use high-quality combed cotton that feel soft against the skin while helping to regulate heat and moisture. A touch of elastane delivers gentle stretch, so they keep their shape without digging in.

The fit is carefully engineered. A contoured pouch supports a natural outline, while a smooth, tag-free finish and flatlock seams reduce chafing under jeans or joggers. The soft-brushed waistband sits securely without rolling or pinching for day-long ease.

Built to last, our trunks feature colourfast dyes and durable stitching to withstand frequent wear and washing. Reinforced hems and resilient waistbands maintain fit and structure, so your favourites stay in rotation for longer.

From classic black, navy and grey to seasonal shades and playful prints, our collection equips your drawer with styles for every mood. Choose supportive mid-rise trunks, longer-leg cuts for added coverage, or lightweight options ideal for warmer days.
