THERMOS Light & Compact 0.5 L Vacuum Flask

The THERMOS Light & Compact 0.5 L Vacuum Flask is a portable container designed to keep hot and cold drinks at temperature during outdoor activities and daily commutes. It holds 0.5 L, which suits personal hydration needs. The vacuum-insulated construction uses two stainless-steel walls with a Thermax vacuum barrier to limit heat transfer. This design keeps liquids hot for up to 12 hours and cold for up to 24 hours. It is suited to hiking, camping, and travel where reliable temperature retention matters.

The flask has a stainless-steel body built to withstand outdoor use. The integrated cup lid lets you serve drinks straight from the container. The automatic pour-through stopper releases liquid without having to be fully removed. It can also be taken apart for easier, more thorough cleaning. The compact shape fits easily into backpacks, and the grey finish gives it a neutral look that blends with standard gear.
