Frequently Asked Questions
Why is SUS316 stainless steel better for a sports bottle than standard 304?
SUS316 is a medical-grade alloy that contains molybdenum, which provides significantly higher resistance to salt-pitting and chemical corrosion compared to SUS304. For sports enthusiasts using functional beverages or tea, 316 ensures the inner liner remains odor-free and safe from long-term erosion, extending the bottle's life.
Is the 1000ml large capacity bottle too heavy for daily carry?
Our 1000ml flask is engineered with a high-strength yet lightweight double-wall structure. While it holds a massive 33oz of liquid, the integrated ergonomic carry loop makes it easy to carry with one finger or clip to a bag, making it a favorite for commuters and hikers.
How do you clean the one-touch lid and internal straw?
Effortless hygiene is a core design feature. The entire lid assembly, including the food-grade silicone straw and sealing rings, can be easily detached for a thorough deep clean. The wide-mouth design of the 316 series also allows for easy ice filling and manual scrubbing.
What certifications do Gencore sports bottles provide for wholesale?
Compliance and safety are our top priorities. All Gencore sports drinkware is rigorously tested and fully certified with FDA, EC, LFGB, and BPA-Free standards, ensuring safe market entry and clearance for global B2B projects.
