Morning or evening sips are yours with the Fellow Rocky Tumbler. An insulated stainless steel to-go mug, the Rocky is designed for coffee and cocktails both. The Rocky's 10-ounce capacity, ceramic inner coating, weighted base, and wide opening for ice cubes make it ready for any drink recipe you can think of. Best of all, Fellow's 'pebble' swivel lid offers splash resistance on the go and easy one-hand opening and cleaning.
