The Gymshark Onyx 5.0 Seamless T-shirt Black/Light Grey is a performance tee crafted from premium breathable textured mesh.

Gymshark is a British athletic apparel retailer founded in 2012, which began by selling supplements. Gymshark added apparel in 2013, and the brand is noted for its physique-enhancing apparel, styled to be worn both in and out of the gym. The Black/Light Grey Gymshark Onyx 5.0 Seamless T-shirt pairs a black base with Carmine Red at the pecs, raglan sleeves, and center front rubber logo. A seamless finish extends to the hems, and Be A Visionary branding appears on the interior. The 5.0 Seamless T-Shirt features raglan sleeves to make the shoulder musculature appear more massive.

Our experts feel that the best feature of the 5.0 T-shirt is its heavy-duty compression, which gives the feeling of an instant boost in strength.
