The shirt is finished with the distinctive Onyx textured panelling and geometric detailing across the chest, shoulders and back, giving it the signature technical look the collection is known for.

Please note: this is the Black/Onyx Grey colourway, which has blue-toned Onyx detailing despite the official Gymshark colour name not describing it as “blue”.

A rare collector’s piece for Gymshark fans, David Laid fans, and collectors of limited Gymshark drops, as well as a standout training top for bodybuilding, weightlifting, gym training or athleisure wear.
