What people are saying
Fits exactly like the photos
Was sceptical about ordering fit online but the muscle cut is real — tight through the chest, not tight everywhere. Ordered a second pack.
Fabric holds up after washing
Had these six weeks, washed weekly, still no sagging around the collar. That's more than I can say for the gym brand ones I paid double for.
Great pack, runs slightly small
Sized up to L from my usual M and it's perfect now. Message support first if you're between sizes, they were quick to reply.
Questions
Questions, answered
It's a muscle fit — closer through the chest, shoulders and arms than a standard tee, with a straighter cut at the waist. If you prefer more room, size up.
Two tees. Choose Black/White (one of each), Black/Black, or White/White at checkout.
Orders are dispatched within 24 hours. UK delivery typically takes 2–3 working days from dispatch, and it's free on every order.
Yes — you have 30 days to send it back for a refund or exchange, no questions asked.
The fabric is pre-shrunk before it's cut, so it holds its size and shape through repeated washes. Wash cold, avoid the tumble dryer for best results.
