Double-wall insulation guarantees a steady temperature for up to 24 hours, and the powder-coated exterior offers a secure hold. A D-shaped handle, powder-coated in the same matte black finish, comfortably fits three fingers. The travel mug holds 11 fluid ounces, has a clear lid with a silicone seal that fits snugly with a retractable sip-hole closure to keep beverages from leaking, splashing, or spilling. As with all stainless steel mugs, hand washing is encouraged.
