Supplier's note

  1. Technical Breakthroughs:

    • The 3-layer TPU construction in Pro models provides 50% thicker reinforcement than base versions, ideal for extreme weather gear.
    • The IPX8 waterproof rating (Pro) triples the industry standard, enabling submersion in water without leakage.
    • Adhesive strength improvements (up to 12N/cm²) ensure secure bonding even on stretchy fabrics like spandex.
  2. Optimal Version Selection:

    • Base Model: Best for casual wear (e.g., everyday jackets) where standard durability and budget constraints apply.
    • Advanced Model: Suited for professional workwear requiring enhanced abrasion resistance and moderate water protection.
    • Pro Model: Tailored for outdoor enthusiasts and military gear, where extreme conditions demand maximum durability and submersion-proof sealing.

With the Pro model’s IPX8 rating, you can ensure jackets withstand heavy rain or accidental submersion. Pair its triple-layer TPU with high-strength adhesive to eliminate seam failures, delivering unmatched user confidence in harsh environments.
