A classic crewneck sweatshirt delivered in a heavyweight reverse-weave cotton. Featuring custom graphics for London '25. New without tags - if you know Tracksmith, you know they do not have tags on their clothing. My wife bought this for me because I am running the London Marathon, but it is just a bit too tight on me. Size: Medium - See Photo Of Size Tag and measurements; ~21" armpit to armpit across the chest and ~25" from neckline to hem, as well as screenshots from the Tracksmith website - seems to be unisex sizing.
