This Contigo coffee travel mug is so much more than a statement piece, thanks to THERMALOCK double-wall vacuum-insulated stainless steel, which keeps drinks hot up to 6 hours or cold up to 12. Plus, its one-piece SNAPSEAL lid is leak-proof when closed for on-the-go convenience and allows for one-handed drinking with no lids or caps to remove or misplace. At the end of the day, remember to hand-wash all parts and let them air-dry with the lid off.
