## Long description

The SIGG IBT Obsidian 0.75 L Black vacuum flask is a double-walled stainless steel thermo bottle designed to keep beverages hot or cold for extended periods. With a capacity of 0.75 L, a slim diameter of 7.6 cm and a height of 267 mm, this lightweight flask (342 g) combines durability and a compact form factor for everyday use. The bottle is BPA-free and features copper-coated inner walls and vacuum insulation to optimise temperature retention while maintaining a slim profile.
Advantages
The double-walled 18/8 stainless steel construction with a vacuum layer and copper inner coating provides efficient thermal insulation for both hot and cold drinks. An ultra-thin inner body achieved by precision spinning technology reduces the flask's weight by about 30% compared with standard insulated bottles, while high-precision welding minimises the vacuum gap. Embossed grooves on the outer surface increase structural strength and resistance to deformation. The screw cap can be used as a drinking cup, supporting convenient use outdoors and on the move.
Suitable for
Hiking and trekking
Commuting and daily office use
Cycling and mountain biking
Canoeing, boating and other water activities
Outdoor trips, picnics and camping

How to use
Preheat or precool the flask by filling it with hot or cold water for a few minutes and then emptying before adding your beverage. Secure the screw cap tightly to maintain vacuum insulation and prevent spills. Use the cap as a cup for pouring and drinking; pour slowly to avoid splashing. After use, rinse the interior with warm water and mild detergent. Allow all parts to dry thoroughly before reassembly and storage.
Usage recommendations
Do not place the vacuum flask in a microwave or freezer. Avoid using abrasive cleaners or steel wool on the inner surface to preserve the copper coating. For best thermal performance, avoid frequent opening and keep the cap closed as much as possible. Handwashing is recommended to maintain finish and insulation properties.
