Copco Urban Professional Travel Mug, $10
If you trip on flat pavement, this mug's for you. You can turn it upside down and shake it without losing a drop, thanks to the spillproof lid. A dent-resistant rubber sheath makes losing your grip nothing to worry about, either. Hand wash.

Size: 16-ounce capacity; 2 3/4-inch base diameter.
