Carhartt 105419 is a versatile shirt jacket (shacket) that functions as both a heavy-duty shirt and a light jacket. The robust canvas fabric is lined with soft fleece, giving the garment good warmth on cool days. It is ideally suited as a mid-layer at work, an outer layer during transitional seasons, or an everyday garment in cooler climates.

The material is an 8.5 oz canvas blend of 98% cotton and 2% spandex with Carhartt's Rugged Flex stretch technology. This provides natural freedom of movement when bending, reaching or lifting. The Relaxed Fit offers plenty of room without becoming awkwardly oversized.

The shirt jacket features a spread collar and full closure with Carhartt's characteristic metallic logo snap buttons. It has two chest pockets with snap-button closure – the left with a pen loop and a sewn-on Carhartt badge – as well as two large hand-warmer pockets at the front. The cuffs have two-way snap adjustment with extended flaps for a good fit over work gloves.
