Frequently Asked Questions

Why is a wide mouth insulated bottle preferred for outdoor sports?

The wide-mouth design is the industry standard for adventure gear because it allows for rapid pouring, easy addition of full-sized ice cubes, and high-flow hydration. Furthermore, the 18/8 stainless steel construction ensures the bottle is puncture-resistant and rust-proof, maintaining its integrity in rugged environments.

Yes. Gencore is a certified factory. Our entire production line for wide-mouth flasks holds FDA, LFGB, BSCI, and ISO9001 certifications. This ensures that all materials are BPA-free and safe for the international market, making customs clearance hassle-free for global importers.

Absolutely. We provide both handle lids and straw lids that are fully interchangeable. For B2B orders, we can also customize the lid colors and add your company logo, providing a complete private-label solution tailored to your target audience.

Our industrial-grade powder coating is baked at high temperatures to create a durable, scratch-resistant surface. It prevents exterior condensation (the "no-sweat" effect) and provides a non-slip, comfortable grip even when hands are sweaty or wet during sports activities.
