Black+Blum Explorer Flask Duo: hot or cold for 24 hours
The Black+Blum Explorer Flask Duo keeps drinks piping hot or ice cold for 24 hours thanks to vacuum insulation. Made for hikes, beach days and mountain trails, it has a reinforced steel body and a 100% leak-proof design.
Two double-walled 200ml stainless steel cups screw neatly onto the top and bottom, so you can share a plastic-free brew anywhere. A silicone gasket stops drips, a thick nylon strap makes carrying easy, and the smooth-pour cap minimises spills.
