Pro-Grade Steel. Featherlight Thermal Insulation. Engineered for Action.

Experience the next evolution of athletic hydration with the FEIJIAN Pro-Series Vacuum Insulated Sports Bottle. Specifically engineered for high-performance athletes, gym-goers, and outdoor adventurers, this premium thermal flask strips away heavy bulk without sacrificing an ounce of temperature control. Swapping out standard metals for medical-grade 18/10 Stainless Steel, it keeps your pre-workout ice-cold or your morning coffee piping hot for hours, delivering a pure, crisp taste with absolutely zero metallic aftertaste.

✨ Why It’s an NLW Essential:

• Revolutionary Ultra-Thin 0.15mm Liner: Engineered with cutting-edge manufacturing tech that slashes the inner steel wall thickness down to just 0.15mm (compared to clunky 0.5mm standard bottles). This gives you maximum fluid capacity while keeping the bottle incredibly lightweight—only 255g!

• Elite Medical-Grade 18/10 Stainless Steel: Crafted from ultra-pure, rust-proof 18/10 steel with a specialized particle-free mirror liner processing. This creates a brilliantly bright, non-porous interior that resists stains, odors, and bacteria buildup.

• Rapid One-Key Click Open: Designed for high-speed hydration mid-workout. The premium cap features a one-key pop button for instant, one-handed drinking while running, cycling, or lifting weights.

• Rugged Tactile Plastic-Sprayed Surface: Finished with an ergonomic, concave body shape coated in a premium plastic-sprayed matte texture that provides a secure, non-slip sweatproof grip even when your hands are slick.

• 100% Leak-Proof & BPA-Free Cap: Built with a rock-solid, packable locking system using premium Tritan and PP materials that are completely BPA-Free, ensuring your bottle never leaks a single drop inside your gym bag.
