I loved the products when I purchased them just after the company launched but it appears they have since changed their sizing! I have always been a medium in tops and baselayers - including the one I originally bought which I will add now - is a little too big on me as I have lost some weight, however when I treated myself to a new one, I again, purchased a medium and could only just fit myself in. Nothing more devastating than putting on a new base layer bought from the same company in the same size and not being able to wear it without feeling like you’re bursting out of it
