I bought this top for casual wear having had a blue one that lasted well. Within two weeks (two wears and one wash) there was a 5p piece size hole in the armpit. At the same I bought a performance top (Silver) and a similar hole appeared. I’ve emailed MyProtein, who I’ve been using for nearly 20 years, and had no response ... which is a shame as I’m a loyal customer. Just be aware these tops are hit and miss it seems. I’m two tops worse off with no recompense.
