.WAV Swim Trunks

Built for hot drops and hotter days, the ION.WAV Swim Trunks are your dev-approved uniform for beach breaks, off-site retreats, and impromptu flow-state swims. Made from 91% recycled polyester with 4-way stretch, these trunks flex like your schedule and dry faster than a hotfix in prod.

With an anti-chafe inner liner smoother than your CI/CD pipeline, breathable mesh pockets for your essentials, and a stealthy inner stash pocket so you’re free to roam, float, or refactor your tan lines.

Whether you’re catching rays or catching ideas, ION.WAV is your runtime-ready swim gear—optimized for performance, comfort, and cool.
