Our insulated tumblers are constructed from premium 304 food-grade stainless steel (304 SS) for both the inner and outer walls. This ensures the product is durable, rust-resistant, BPA-free, and leaves no metallic aftertaste.

Featuring advanced double-wall vacuum insulation technology, these mugs can keep your beverages ice-cold for up to 24 hours or piping hot for up to 12 hours, making them ideal for all-day hydration.

Yes, the tumblers come equipped with a multifunctional, splash-resistant lid that features a secure straw port, a direct-sip opening, and a full-cover top. A reusable straw is also included with each mug.

We offer these insulated vacuum mugs in both 30oz (approx. 880ml) and 40oz (approx. 1180ml) sizes, allowing you to choose the perfect volume for your daily hydration needs.

Yes, despite their large capacity, both the 30oz and 40oz tumblers feature a tapered slim-base design that allows them to fit securely in most standard vehicle cup holders.

Depending on the option you choose, the tumbler comes with a sturdy, ergonomic integrated handle for easy carrying. We recommend hand washing the stainless steel body with mild soap and warm water to preserve the vacuum seal.
