Why Polyether TPU?

  • Lightweight

    Constructed from advanced 0.3mm polyether TPU fabric for superior aquatic durability. Weighing just 250g for effortless performance without compromising strength.

  • Durability

    Polyether TPU resists hydrolysis and degradation for extended lifespan and reliable open-water performance. High-tenacity fabric delivers exceptional tear strength in a lightweight design for professional sports applications.

  • High-Visibility

    Designed in ultra-bright fluorescent colors to enhance swimmer visibility in open water environments. Improves safety awareness for boats, lifeguards, and fellow swimmers.

  • Sustainable

    Extended lifespan reduces waste and environmental impact. Polyether TPU resists hydrolysis and UV degradation far better than conventional materials—fewer replacements, cleaner oceans.
