Built for the outdoors, the Black and Blum Explorer is the heavier-duty end of the brand's steel bottle range, made for conditions where a bottle takes knocks. The large size holds 850 ml and stands 23.4 cm tall, and full vacuum insulation keeps drinks hot or cold for hours rather than minutes.

Two details define the drinking experience. The rim is smooth with the thread set on the inside, so there is nothing sharp or ridged against the lip when you drink straight from the bottle, and the lid is 100 percent leak-proof, which matters when the bottle rides in a rucksack alongside a laptop or a camera. The stainless steel and nylon construction is made to last for years, and the bottle is handwash only. It comes in green, olive green and orange, and is supplied in a gift box.

An 850 ml capacity suits people who are away from a tap: field engineers, logistics and site teams, outdoor and adventure event participants, and sports club or sponsorship gifting. It is also a solid corporate gift for companies running hydration or single-use plastic reduction initiatives.
