The Chelsea 1997–99 Home Long Sleeve Jersey by Umbro is a masterclass in late-90s Premier League design, embodying an era when tradition met innovation. The deep royal blue base is enriched with alternating jacquard textures, offering a sophisticated vertical stripe effect that catches the light subtly and adds tactile dimension.
 
The shirt’s construction features long sleeves with pronounced white panels and yellow-black piping running down the raglan shoulders and arms — a sharp contrast that gives the kit a streamlined, athletic silhouette. The collar is a standout element: a structured, fold-over design in white with navy and yellow stripes, exuding a crisp, retro elegance. The inside of the collar is inscribed with “CHELSEA F.C.” in fine detail, a subtle yet premium nod to club identity.
 
Autoglass branding is printed prominently across the chest in bold white with black outline, typical of the era’s emphasis on commercial clarity. The Umbro logo is embroidered cleanly, while the lion-crest badge — a precursor to Chelsea’s modern emblem — is a nostalgic symbol of the club's transitional years.
 
Performance-wise, the "Vapa-Tech" label and mesh panelling along the back demonstrate the integration of breathable technology, a hallmark of late-90s kit engineering.
 
This jersey is a quintessential piece of Chelsea’s late-90s identity — bold, structured, and rich in legacy.
