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.
"This flask is amazing for keeping drinks at the perfect temperature, whether Iโm out with the kids or on a busy day. I love knowing Iโm avoiding plastic bottles while having something so reliable by my side." - Georgie x
