I bought a tank top on the first day the online store opened. I live in Japan where they don’t ship to but they agreed to ship it to the Ireland thinking that it fell under the UK umbrella and my mother sent it to me in Japan. I have worn it at least once a week since then and it is in perfect condition. I want to buy more Tracksmith gear but the exchange rate (esp. at the moment) makes it a bit too pricey.
I do have some NIKE and Adidas tops that have lasted many years too but they are not quite as comfortable as my Tracksmith tank top.
