Get kitted out for the new season by heading to the London Stadium Store before Saturday's game against Manchester City.
The store will be open from 9am for you to check out our full range of 1980 FA Cup-inspired 2019/20 Umbro replica kits, training wear, Hammers fashion, gifts and more.
Make sure you head to the store early, as we expect it to be very busy in the run-up to kick-off on Saturday. We'll be open after full-time too.
We'll also have a pop-up shop located between turnstiles H and J, open from 10am to kick-off, at half-time and after the game.
Remember you can shop 24/7 at officialwesthamstore.com too.
