The Bioloco Explorer Cup is a double-walled stainless-steel thermal mug for coffee, tea, or anything you'd carry in a travel mug — but built for actually carrying. The handle clips onto a backpack strap, the threaded drinking lid stays sealed against spills in transit, and the recycled-stainless construction keeps drinks hot for hours and cold for longer. From Chic Mic, the European brand behind Bioloco's sustainable everyday goods.
