Thermos Sigg Alpine Star Roasted Green 0.75 L — vacuum-insulated bottle, stainless steel

The Sigg Alpine Star Roasted Green 0.75 L is a vacuum-insulated stainless steel bottle designed to maintain beverage temperature for extended periods. With a 0.75‑liter capacity and screw-top closure, this thermos combines a durable exterior finish with a compact shape that fits in many bag compartments and vehicle cup holders. The double-walled vacuum construction reduces heat transfer to keep hot drinks hot and cold drinks cold, while the stainless steel interior resists staining and odor retention.

Advantages

The thermos provides reliable thermal retention for both hot and cold beverages thanks to its vacuum-insulated stainless steel body. The screw-top lid ensures a secure, leak-resistant closure during transport. Its 0.75 L capacity offers a balance between volume and portability for daily commuting, outdoor activities and travel. The exterior finish is designed to be robust against light abrasion and suitable for repeated use.

Suitable for

• Keeping coffee or tea hot during commuting or office hours
• Storing cold drinks and water for outdoor activities and hikes
• Travel and long journeys where temperature retention is needed
• Everyday use at home, work, or school

How to use

Preheat or precool the thermos by filling it with hot or cold water for a few minutes, then empty before adding your beverage to improve temperature retention. Fill the bottle without overfilling, close the screw-top lid firmly and check the seal before placing it in a bag. To pour, unscrew the lid and pour directly or use the lid as a temporary cup if designed for that purpose. Allow hot liquids to cool to a safe drinking temperature before consumption.

Usage recommendations

Clean the stainless steel interior after each use with warm soapy water and a bottle brush; avoid abrasive cleaners that may damage the finish. Do not place the thermos in a dishwasher unless the manufacturer indicates it is dishwasher-safe. For best performance, avoid filling with carbonated beverages and do not use in microwave ovens. Store with the lid removed to allow the interior to dry completely.
