Ultralight. No new plastic. 110% offset. The future of sustainable drinkware is here.

MiiR's new Climate Positive range uses 25% less stainless steel, no new plastic and its carbon footprint is offset 110%. Despite a lighter weight and fewer materials, the Tumbler maintains its Thermo 3D® double-wall vacuum insulation, ensuring your hot drinks stay warm and your cold drinks remain ice cold. Plus, it's topped with a press-fit slide lid, helping lock in temperature for that bit longer when you're on the move. 

Perfect for everything from takeaway brews to or group cocktails, the Tumbler is available in 12oz and 16oz sizes and you can choose between a black or silver finish.
