Kaikanialeʻa Boys’ Boardshorts: Built for Boundless Adventure

Engineered for the restless, adventurous spirit of keiki, the Kaikanialeʻa Boys’ Boardshorts are designed to handle everything from reef breaks and skate parks to long, sun-drenched days on the shoreline. Crafted for durability and effortless movement, these boardies are built to keep up with the pace of childhood.

Purposeful Design

Crafted from premium bielastic fabric, these shorts offer superior 4-way stretch and a quick-dry finish that resists pilling, sun creams, oils, and chlorine. The design features a flat waistband with a dolphin-style hem for extra flexibility, and an internal velcro square to ensure a secure closure during active play.

Care Note: While this fabric is exceptionally durable, please be mindful that high-performance recycled textiles can still snag when sliding against very rough or abrasive surfaces (such as raw concrete or jagged rock).

An Inclusive, Long-Lasting Fit

We designed the Kaikanialeʻa Boardshorts with a generous, inclusive fit to comfortably accommodate growing keiki. Featuring a discreet, adjustable internal waistband that can be tightened down by two full sizes, these shorts are built to grow with your child, providing a reliable, long-lasting fit. If you prefer a more tailored, snug feel, we recommend sizing down.

A Commitment to Our Oceans

Every thread of the Kaikanialeʻa Boardshorts tells a story of restoration. This piece is crafted from a sophisticated blend of two premium recycled materials: regenerated nylon, salvaged from abandoned fishing gear, and high-performance recycled polyester, repurposed from ocean-bound plastic waste. By harmonizing these circular materials, we create a textile that is not only durable and salt-resistant but also actively restorative. From the recovery of these plastics to the final sustainable textile creation, every step is engineered to minimize environmental impact and breathe new life into discarded materials.

Built to Last

With reinforced stitching throughout, these boardshorts are engineered to withstand endless beach days, skate sessions, and the wildest of childhood adventures. They are designed to be a reliable, long-lasting staple. Care is effortless: simply hand-rinse in fresh water and hang to air dry—no washing machine required. Choose a swimsuit that lets your keiki explore the big, beautiful world while actively contributing to the health of the very beaches where they play.
