In Birkdale, Abacus presents a modern and functional version of the traditional track jacket. Abacus has combined the retro feel with all the modern features you could want, such as breathable material, moisture-wicking properties, lightly padded panels on the upper chest and back for extra warmth and of course stretch to offer full freedom of movement. The jacket is black, has side pockets and a soft brushed fleece on the inside of the high collar.
