A remarkably light vacuum flask for mountain use
Montbell says:
Achieves an ultralight weight with highly corrosion-resistant, flavor-neutral titanium. Combined with an insulated inner cap to deliver excellent thermal efficiency to keep hot drinks hot and cold drinks cold for longer. Comes with anti-slip grooves in the outer cap and a hexagonal-shaped inner cap to allow for easy opening even with gloves on. An optional Active Lid (sold separately) is also available.
Our Verdict
At 269g for 750ml, the Titanium Alpine Thermo Bottle stands out for how little it weighs while still offering proper vacuum insulation. Montbell rates it to keep water at 75°C or above after six hours, which I think is a strong result for something this light.
The double-wall titanium construction keeps weight down and resists corrosion, while the insulated inner cap helps reduce heat loss through the neck. I also like the glove-friendly design, with anti-slip grooves on the outer cap and a hexagonal inner cap that is easier to grip in cold conditions.
