Thermos SIGG Alpine Star Double-Wall Vacuum Insulation Roasted Green 0.5L

Thermos SIGG Alpine Star Double-Wall Vacuum Insulation Roasted Green

Insulated Thermos SIGG Alpine Star Roasted Green 0.5L is a technical vacuum flask engineered for mountain trekking, hiking, and professional outdoor utility. This beverage container is constructed from 90% recycled stainless steel to provide a durable, BPA-free solution for maintaining hydration in various climates. The integrated double-wall vacuum insulation features an inner copper coating to ensure high-level thermal performance across extended durations. This specialized copper-plated layer works by reflecting thermal radiation back into the liquid, which significantly minimizes heat transfer through the vacuum gap. It effectively keeps contents hot for up to 15 hours or cold for up to 56 hours regardless of external environmental conditions.

Features

• ➤ High Thermal Retention: Maintains beverage temperatures for 15 hours hot and 56 hours cold using advanced vacuum technology.
• ➤ Sustainable Construction: Manufactured with 90% recycled stainless steel to ensure high impact resistance and environmental responsibility.
• ➤ Twist&Pour System: Features a specialized rotating cap that allows for precise pouring into the cup without the need to fully unscrew the stopper.
• ➤ Carbonated Safe: Designed with a high-pressure seal that remains completely leak-proof even when carrying carbonated beverages.
• ➤ Enhanced Stability: Includes a protective silicone base and anti-slip grooves to provide a secure grip and prevent sliding on uneven surfaces.
• ➤ Lightweight Profile: Weighs only 305g with a slim 68mm diameter, making it compatible with most standard backpack side pockets and bottle holders.

When navigating the windswept ridges of the Tatra Mountains in Italy, maintaining core temperature through hot hydration is essential for safety and performance. The SIGG Alpine Star serves as a reliable heat source during rest periods at high-altitude shelters where air temperatures drop rapidly. Its integrated silicone base ensures the flask remains stable on frozen rock surfaces or damp wooden trail benches during equipment transitions. The Twist&Pour system explicitly prevents internal heat loss by allowing the user to fill the cup while keeping the main vacuum chamber mostly sealed against the cold mountain air.
