XUDREZ Thermal Flask 1000ml insulated water bottle 🚰

This stainless steel thermal flask keeps drinks hot or cold for long periods, merging robust construction with a leakproof lid for travel, gym and outdoor use. If you need an insulated water bottle 1000ml for long days away from home, this yellow 1-litre flask offers convenient pouring and a cup-style lid for sipping on the move.

Key Points

The flask features a double-wall vacuum design that reduces heat transfer and helps maintain beverage temperature for many hours. According to the manufacturer, it can retain around 83°C after six hours and about 64°C after 24 hours when filled with boiling water at room temperature, which makes it useful for coffee, tea and other hot drinks. For cold drinks, the same insulation slows warming and keeps refreshment cooler than a single-wall bottle.

The lid has a leakproof locking mechanism and a press-to-pour action, so you can open and pour without fully removing the stopper. A built-in filter is included for loose-leaf tea or infusions, and the top cover doubles as a cup so you do not need extra cups when hiking or commuting. The bright yellow finish is easy to spot in a backpack or at the gym 🟡.

Practical capacity options are available beyond 1000 ml, including 800 ml and 1500 ml, so you can choose the size that matches your routine. The flask is described as BPA-free and environmentally friendlier than single-use bottles, and the materials are selected with hygiene in mind.

Usage Recommendations

For best thermal performance, pre-warm or pre-cool the flask by rinsing with hot or cold water before filling, this helps reduce initial heat loss. The lid should be cleaned regularly, and removable parts such as the tea filter can be washed separately to avoid residue buildup. When carrying in a bag, secure the cap using the lock to prevent accidental opening, especially with carbonated or alcoholic drinks.

Consider that, according to the manufacturer, temperature retention figures are measured under standard conditions and may vary with ambient temperature and how often you open the flask. The flask is sturdy but will develop dents if dropped onto hard surfaces, which can affect the vacuum insulation over time. ☕🥾.
