FAQ
Frequently Asked Questions
We recommend hand-washing. While our stainless steel is tough, the high temperatures and harsh chemicals in modern dishwashers can degrade the vacuum seal and strip the exterior finish over time. A quick rinse with warm, soapy water is all it takes to keep your Kargen looking and performing like new for years to come.
Absolutely. The Kargen is designed to be the ultimate road-trip companion. Its slim, ergonomic base is engineered to fit 99% of standard vehicle cup holders, so you won’t have to deal with it rolling around on your passenger seat during a commute.
Not at all. We use an electropolished interior—a specialized process that smoothes out the microscopic "peaks and valleys" of the stainless steel surface. This ultra-smooth, passive finish prevents the metal from leaching flavor into your drink and stops residual odors from clinging to the bottle. Every sip tastes exactly how it should: clean, crisp, and pure.
Yes, it’s slim, lightweight, and incredibly easy to carry wherever you go, making it a perfect companion for your daily adventures.
