Premium 500 ml double-walled stainless steel thermo bottle in matte black. Keeps your yerba mate at the perfect drinking temperature (70–80 °C) for 4–6 hours, with no reheating and no over-extraction. Pairs beautifully with a 1-litre French press session — fill the bottle with what you brew and carry the rest of your mate through the day. Vacuum-insulated, leak-proof cap, ergonomic shape. The single accessory that has changed how we drink mate on the road.
