Men’s Performance Swim Trunks
Full honesty: these trunks are the last item in our store that isn’t made in the USA. They’re left over from before we went all-in on American-made. When they’re gone, they’re gone — and everything we sell will be made here, no exceptions.
Built for the water. Broken in for everything after.
Four-way stretch, water-resistant fabric that dries fast, and a cut that sits about 3–4″ above the knee — so the quad gains get their moment and you stay comfortable all day, on the boat, at the beach, or at the lake. They double as gym shorts, too.
• 4-way stretch — extreme comfort for long days on the water
• Water-resistant material — dries much faster than traditional swim trunks
• Extra-stretch waistband — no belly squeeze when you sit down
Fit: true to size. Wear a large in other swim trunks or shorts? A large here fits the same way.
Trust us — these will be your new favorite swim trunks. 👊🏼
