Grown from genetically-modified axolotl cells
Each living garment repairs small tears overnight and creates a perfect custom fit as the cells respond to your movement patterns in water. Buy once, wear forever.
You come home from surfing, notice a small tear in your suit, hang it up, and wake up to find it's completely healed itself overnight — the fabric literally regenerated like living skin. It's now also subtly reshaped around a new muscle group you've been building.
