The BN3TH Pro Agua X Boxer Brief is the ultimate water-performance base layer engineered to be worn under boardshorts. Featuring patented 3D Pouch technology and rapid-drying hydrophobic fabric, it completely eliminates wet-suit and swim trunk chafing. Read more.
The BN3TH Pro Agua X Boxer Brief is specifically engineered to be your first layer of defense against wet-suit rash and boardshort friction. Designed to be worn underneath unlined swim trunks or wetsuits, these high-performance aquatic briefs swap traditional materials for an advanced, water-shedding hydrophobic matrix. They stay perfectly locked in place whether you are launching off the wake on Kalamalka Lake or paddleboarding around Vernon.
The Original 3D Pouch™: Naturally cradles, lifts, and separates your anatomy to entirely eliminate skin-on-skin friction and painful chafing, even when completely soaked.
Hydrophobic Quick-Dry Fabric: Woven from a specialized lightweight poly-spandex blend that sheds water rapidly, preventing heavy drag and drying instantly back on the boat deck.
No-Ride Compression Fit: Tailored to hug the thighs securely without bunching, rolling, or sliding down during high-impact water activities.
Flatlock Anti-Chafe Seams: Assembled with ultra-smooth, flat interior stitching placed strategically away from high-friction zones to keep your skin irritation-free.
Most premium boardshorts don't come with built-in mesh liners, which often leads to inner-thigh friction. The Pro Agua X is a favorite at Attridge because it acts as a frictionless second skin. It allows you to transition seamlessly from active wakesurfing or foiling straight to the lakeside beach volleyball courts in the Okanagan heat without needing to change your base layer.
