Whether it’s a stiff coffee or cold beer kind of morning, the 20oz Headwaters™ Mug treats beverages right, with double-wall vacuum insulation that keeps liquids hot up to 8 hours or chilled up to 24. Premium food-grade stainless steel construction is 100-percent BPA free. A tough powder-coat finish—with laser-etched Simms logo—eliminates sweating. And a secure, clear-plastic lid does the same for spilling. Dishwasher safe.
