Dubblin Knock Out 850ml Black Vacuum Flask – Large Capacity Insulated Bottle
Built for people who'd rather carry one large bottle than refill a small one all day, the Dubblin Knock Out 850ml Black vacuum flask is a genuinely large-capacity option in Dubblin's insulated range. Its double-wall vacuum insulated stainless steel body keeps beverages hot for up to 12 hours and cold for up to 24 hours, and the true 850 ml capacity comfortably covers a long work day, a gym session, or a day of travel. The matte black finish gives it a solid, professional look.
The Knock Out is built with an anti-skid base and a leak-proof lid, both practical touches for a bottle this size that's likely to be carried in a bag or set on a desk for hours at a time. Its BPA-free steel body holds up to daily use without rusting or affecting the taste of what's inside.
