The Peninsula doesn’t do flimsy swimwear—these trunks are built for saltwater sessions that start with cannonballs and end with oyster-shucking contests. Made from recycled polyester with four-way stretch, they shed water faster than a sea otter’s back, while the anti-chafe liner keeps you moving when the waves get rough or the beach logs get competitive. The UPF 50+ fabric laughs at sunburn, and the mesh pockets drain sand between rounds of frisbee.
Tuck your truck keys in the hidden valuables pocket—because the only thing that should get lost is your dignity after that failed backflip.
Fabric Details:
91% recycled polyester, 9% spandex outer with quick-dry microfiber. Lined with breathable mesh (92% poly/8% spandex US, 90% poly/10% elastane EU). 5.13 oz weight for agility without transparency.
