When choosing a swim buoy for open water training, most people focus only on size or color. But the real difference lies in the material. Today, the market is filled with buoys made from 100% PVC or TPU Polyester film. While they may look similar at first glance, their performance and durability are very different.
PVC (Polyvinyl Chloride):
The cheapest option, but also the least reliable. PVC becomes brittle under sunlight, has limited lifespan, and is far from eco-friendly.
TPU Polyester:
A step forward from PVC, TPU Polyester offers better flexibility. However, it still suffers from hydrolysis problems in humid or wet conditions. Over time, the material weakens and breaks down, reducing safety.
TPU Polyether:
This is the advanced solution we use for our buoys. TPU Polyether offers superior hydrolysis resistance (durability), meaning it does not degrade easily when exposed to water, sweat, or humidity. It keeps its elasticity and strength far longer than PVC or TPU Polyester. Combined with its eco-friendly profile and premium feel, TPU Polyether is the material trusted for professional-grade swim gear.
At Safe Swim Gear, we believe swimmers deserve more than disposable PVC products. Our TPU Polyether buoys are built to last, providing both safety and sustainability for open water athletes around the world.
