Lifeventure TiV Vacuum Insulated Titanium Flask, 500 ml, Dark Grey

Most flasks rely on stainless steel for both inner and outer walls, but the Lifeventure TiV breaks that mould with a genuine titanium outer shell. This rare material choice cuts weight by roughly 40% compared to equivalent stainless steel flasks, yet it remains remarkably tough—resisting knocks, scratches, and corrosion even with acidic drinks like coffee or fruit infusions. At just 500 ml capacity, it is an ideal companion for ultralight backpackers, climbers, and anyone who counts every gram.

Highlights

• Ultra-lightweight titanium body: approximately 40% lighter than equivalent stainless steel flasks.
• Double-wall vacuum insulation keeps drinks hot for up to 8 hours or cold for up to 24 hours.
• 18/8 food-grade stainless steel inner wall ensures no metallic taste and easy cleaning.
• Leak-proof pour-through stopper with silicone seal—no need to remove the lid completely.
• BPA-free polypropylene lid and silicone components; all materials are food-safe.
• Powder-coated dark grey finish provides a secure grip and resists scratches.

In daily use

The wide mouth accommodates ice cubes and simplifies filling, while the pour-through stopper allows controlled drinking without removing the lid. The titanium outer layer is naturally corrosion-resistant and will not rust, even with acidic drinks like coffee or fruit infusions. Hand washing is recommended to preserve the powder coating and vacuum performance. The flask's slim 70 mm diameter fits most car cup holders and backpack side pockets.
