Borussia Monchengladbach Home Shirt 1998/99 #15 L/S Player Issue (XL) is a long-sleeve home shirt produced by Reebok for the 1998/99 Bundesliga campaign. This Borussia Mönchengladbach shirt comes from a difficult season in the club’s history, as the side finished 18th and suffered their first ever relegation from the Bundesliga during a challenging period for the German club.
The design features a white base with a subtle tonal geometric pattern, complemented by black and green detailing across the shoulders and sleeves. A green-trim polo collar and matching green sleeve cuffs frame the long-sleeve construction, while the Belinea sponsor sits prominently on the front alongside Reebok branding. The number 15 appears on the back, and the shirt reflects the late-1990s style seen on the Borussia Mönchengladbach 1998/99 football shirt and other Reebok Borussia Mönchengladbach jersey releases of the era.
