Ever wondered why some swim buoys deflate after a season while others last for years? The secret is in the material.
Most swim buoys use PVC or standard TPU — materials that slowly break down when exposed to water, sweat, and sun. It's called hydrolysis, and it's why your buoy might feel less firm over time.
We took a different approach. Polyether TPU is the material used in medical devices and industrial equipment that need to survive extreme conditions. It resists water breakdown, stays flexible in cold water, and maintains its shape season after season.
The catch? It's incredibly difficult to manufacture. Only a handful of factories worldwide have the expertise and equipment to work with it. That's why most brands don't use it — it's expensive and complex.
With 20 years of manufacturing experience, we're the only brand that builds swim buoys entirely from Polyether TPU. Professional-grade protection for every swimmer.
What Polyether TPU Does Better
✓ Resists water breakdown — Unlike standard materials that degrade from moisture and sweat
✓ Lasts for years — Not just one or two seasons
✓ Stays flexible in cold — Performs in any water temperature
✓ Handles rough conditions — Abrasion-resistant for real-world use
✓ Medical-grade quality — The same reliability standard used in life-critical applications
Why it matters:
Your swim buoy is safety equipment, not just an accessory. Material failure in open water isn't inconvenient — it's dangerous. Polyether TPU eliminates the risk of air leakage, seam failure, and premature wear.
For serious open water swimmers, it's the difference between gear you trust and gear you worry about.
