Boston Marathon runners tend to be easy to spot on Marathon Monday, as many often are seen wearing their official marathon jackets around the city.

Adidas has manufactured these official jackets since 1991, and to commemorate their 25th year of doing so, the 2016 design is a throwback to the original.

For the men, that means a teal (or “equipment green” in Adidas-speak) jacket with black accents, while the women’s version swaps out the black for pink.
