The straight. The one before the turn, the one where you let go of everything, the one where you see what the machine is really made of. The "Flatline" t-shirt by Morex Custom bears this name as a statement. On a black background, the back print stands out: bright red, cream beige, "Race Cup" above, "Designed to Ride" below. A racing plate worn on the back. Simple in front, definitive behind.

"Race Cup": when racing is displayed without complexes
The "Flatline" back graphic directly borrows from the designs of vintage cups and championships. These structured frames were found on race posters, engraved trophies, and official meeting programs.
The deep red and cream beige form a palette that immediately refers to the 60s and 70s, the golden age of racing where visuals were hand-drawn and printed in two colors for lack of better options.
Morex Custom has precisely adopted these codes, without sweetening them. The result is a print that could have come from an archive, except that it is new, and that is exactly the desired effect.

Black as a playground
The black of the "Flatline" t-shirt is not a neutral background; it's a choice of contrast. On the lighter t-shirts in the collection, the prints play on warmth and light. Here, black absorbs everything except what it is asked to show. The red of the racing frame stands out with an intensity that white or beige would not have allowed.
In front, the "Morex Custom" logo in fine, clear typography plays it discreetly, almost an author's signature rather than a commercial hook. The whole works through controlled contrast, not accumulation.
260g cotton: the weight that makes the difference
The same material requirement as for the entire range: a 260 gsm cotton that immediately gives the piece its physical presence. A t-shirt that has weight in your hands, that falls straight without wrinkling, that keeps its shape after washing.
The "Flatline" regular fit is designed to work on its own, no need for layering, no need for a particular context. Black, structured, effective.
Morex Custom at Blackpines: racing heritage in all circumstances
The "Flatline" t-shirt is the Morex Custom piece that speaks most directly to the rider who knows their references. No metaphor, no detours, a competition visual, a slogan, a color. At Blackpines, we selected this piece because it embodies without ambiguity what the two brands have in common: a relationship to mechanics and racing that is not a posture, but an obvious fact.
