Imperium Fiber
Wellness Swimwear
Chlorine-tolerant, quick-drying, shape-retaining swim fabric — the performance of synthetics without the microplastics.

Stands up to pools and salt water without breaking down.
Quick-Dry & Stretch
Shape-retaining recovery that endures countless dips.
Zero Microfibers
No plastic fragments shed into oceans or pools.
Design swimwear that gives back
