BB Steel Explorer Bottle 850ml, Marine

The Black and Blum Explorer flask, with its 850ml capacity, is a reliable companion for travel and outdoor activities. Its stainless steel body uses vacuum insulation, which keeps drinks hot for up to 12 hours and cold for an impressive 24 hours. A dependable screw-top lid ensures it can be carried safely. Thanks to its large capacity, it provides plenty of fluids for longer trips.

Vacuum insulation for a stable temperature

The core of the Black and Blum Explorer flask is its stainless steel construction, which utilises vacuum insulation. A vacuum is created between the two walls of the bottle, minimising heat transfer and effectively maintaining the original temperature of the contents. This means a hot drink stays warm for 12 hours, while a cold drink will keep its temperature for up to 24 hours. The reliable screw-top lid is completely leak-proof, so you don't have to worry about liquid spilling into your backpack or bag.
