Kellogg's outfit is an outfit-type item in Fallout 4.
A rugged, durable suit of armor devised by Kellogg for himself. It combines a simple, zipped-up leather jacket with durable trousers and heavy boots, worn over a regular work shirt. Kellogg improvised the webbing and kept it as simple as possible, with a simple leather belt with utility pouches worn casually over the waist, a knife sheath over the right thigh, and most noticeable, a large, armored brace for his left arm, kept in place by a torso strap and shoulder pad.
A statement of style over function, Kellogg's armor is good early on, but its inability to accept lining quickly relegates it to the role of a curio.
