Mercer+Mettle Deep Black Stretch Jersey Long Sleeve Shirt

The Mercer+Mettle Deep Black Stretch Jersey Long Sleeve Shirt represents the brand's signature colorway in one of the most versatile and enduring formats in professional apparel. Deep Black is the Mercer+Mettle flagship color -- a rich, true black that photographs cleanly, pairs with every brand palette, and projects a modern, professional confidence that few other colors can match.

For teams and organizations building a branded wardrobe with long-term staying power, Deep Black is the anchor piece that works across every context and occasion. Built on the stretch jersey platform shared across the style family, this shirt delivers four-way stretch that accommodates natural professional movement throughout the day.

The lightweight jersey knit is breathable enough for active use while structured enough to present cleanly in professional settings. The smooth, uninterrupted surface of the Deep Black solid colorway makes it one of the most decoration-friendly options in the family, accepting screen print logos and graphics with clarity and contrast.

The long sleeve format adds coverage and reinforces a considered, professional aesthetic that distinguishes this shirt from casual tees. Deep Black in a long sleeve cut is a particularly strong choice for executive gifting programs, onboarding kits, and branded merchandise collections where the goal is to project a high standard of quality through every piece.

SWAGHQ offers custom screen print decoration on the Mercer+Mettle Deep Black Stretch Jersey Long Sleeve Shirt with minimum orders starting at 12 to 24 units and a two to three week production turnaround. This is the colorway that anchors the collection -- and for good reason.
