Thermos ESBIT Vacuum Flask 1L, olive green

ESBIT Vacuum Flask 1L in olive green is a double-wall insulated thermos engineered to maintain beverage temperature during outdoor activities, travel, work or everyday use. The 1-litre capacity offers enough volume for multiple servings while the vacuum insulation reduces heat transfer to keep drinks hot or cold for extended periods. Its compact cylindrical shape and durable exterior are designed for portability and repeated use in different environments.

Advantages

The vacuum-insulated construction minimises thermal exchange, preserving the temperature of contents without external power. The 1 L capacity balances portability with practical volume for sharing or longer outings. The stainless interior resists staining and odours, and the robust outer finish provides impact resistance and easy handling. The olive green colour is unobtrusive and suitable for outdoor gear.

• Camping and hiking trips where temperature retention is important
• Commuting and travel to keep coffee or tea hot
• Worksites or fieldwork requiring durable drink storage
• Everyday use at home or in the office for hot or cold beverages

How to use

Preheat or precool the flask by filling it with hot or cold water for a few minutes, then empty before adding the beverage to improve temperature retention.

Clean the interior after use following recommended care instructions to maintain hygiene and performance.

Usage recommendations

For best results, avoid placing carbonated drinks under pressure in the thermos and do not use the flask for storing perishable foods for extended periods. Hand-wash the flask with mild detergent and rinse thoroughly; avoid abrasive cleaners. Store with the lid off to allow the interior to dry fully between uses.
