Why You'll Love It
- Unmatched Material Safety: The inner tank is crafted from 316 stainless steel — the same grade trusted in food and industrial applications for its superior anti-rust and anti-corrosion properties. It resists wear from acidic drinks better than ordinary steel, ensuring pure-tasting beverages every time. 100% BPA Free.
- Long-Lasting Temperature Retention: The double-layer vacuum structure creates an airless barrier that stops heat transfer in its tracks. Your hot tea stays steamy and your iced water stays refreshingly cold for hours — even in extreme outdoor temperatures.
- Practical Ergonomics: The slim, streamlined design fits most car cup holders and backpack side pockets. The wide mouth allows easy filling, cleaning, and adding ice cubes or tea bags with no hassle.
- Hassle-Free Cleaning: The smooth, non-stick inner surface rinses clean with warm water. The detachable lid prevents mold and odors, making deep cleaning a total breeze.
- Two Generous Sizes: Choose between 800ml or 1000ml depending on your hydration needs — perfect for short trips or all-day adventures.
