Termoska SIGG 8998.10 0,55 L čierna nerezová oceľ

The SIGG 8998.10 Vacuum Flask 0.55L in Black Stainless Steel is a vacuum-insulated thermos designed for everyday use and outdoor activities. Constructed from high-quality 18/8 stainless steel, it combines durability with a sleek, compact form. The flask holds 0.55 liters, weighs approximately 300 g, and is BPA-free. Engineered to keep beverages hot for up to 13 hours and cold for up to 30 hours, it includes a built-in tea filter, an anti-slip base pad and a user-adjustable Tritan drinking lip that can be positioned for left- or right-handed use. The cap is designed for one-handed opening and closing and the screw mechanism has been improved for a smoother operation compared with previous generations.

Advantages

The flask offers long thermal retention thanks to vacuum insulation, keeping hot drinks hot up to 13 hours and cold drinks cold up to 30 hours. Its 18/8 stainless steel construction provides corrosion resistance and durability while remaining lightweight. The integrated tea filter allows brewing loose-leaf tea or using fruit infusions directly in the bottle. The drinking lip made of tasteless Tritan preserves beverage flavour, and the improved screw cap runs more smoothly and can be operated with one hand. An anti-slip pad protects surfaces and reduces the risk of accidental slipping.

Suitable for

• Commuting and daily office use
• Hiking, camping and outdoor excursions
• Hot beverages such as coffee and tea
• Cold drinks and fruit-infused water
• Replacing disposable bottles and single-use cups

How to use

Preheat or precool the flask by filling it with hot or cold water for a few minutes, then empty before adding your beverage to maximise thermal retention. For tea, place loose leaves in the built-in filter and pour hot water over them; remove the filter or leave it in place depending on desired infusion strength. Use the adjustable Tritan drinking lip for comfortable left- or right-handed drinking. Open and close the cap with one hand when needed; ensure the screw cap is fully tightened to maintain insulation and prevent spills. Hand wash the cap and filter components; the stainless steel body can be rinsed or washed by hand according to manufacturer care instructions.

Recommendations

To achieve the best insulation performance, pre-warm the flask with hot water when carrying hot drinks and pre-chill with cold water for cold beverages. Avoid using abrasive cleaners on the stainless steel surface and do not place the flask in a freezer. Regularly clean the tea filter and cap to prevent residue build-up and preserve flavour neutrality provided by the Tritan drinking lip.
