The Basics Muscle Fit Black Onyx Polo T Shirt is a cotton-viscose blend cut close through the chest and shoulders for a tapered silhouette. The fabric weighs 180 GSM, giving it enough structure to hold its shape without feeling stiff through Indian summers.
The viscose component adds a subtle sheen and breathability that pure cotton won't deliver—useful when you're moving between air-conditioned spaces and heat outside. Single-needle stitching on the seams keeps stress points durable, particularly important in a fitted cut where fabric tension runs high.
Wear this with chinos or joggers for casual office settings, or layer it under an open shirt for structured evenings. It pairs well with our other plain t-shirt designs in your rotation, and the Black Onyx works across the muscle fit range if you're exploring similar cuts. The viscose blend will shrink slightly in hot water—wash in cool and tumble dry low to maintain the fit.
