Thank you for your interest in the product. Please read the following before purchasing. [Product Description] asics Asics META SPEED Meta Speed Singlet Men's M size [Product Condition] I will send you a new item. I have only worn it once over a base layer to check the fit. [Other] Instant purchase is OK. Regarding the fit, I am 178cm tall, 63kg, and have a chest measurement of about 90cm. As is often said, it is a slim fit compared to other manufacturers, but it's not so tight that I can't wear it. It fits well enough that it doesn't flap in the wind. I think this is about right for racing. However, you need to be careful when taking it off because there are countless tiny holes for ventilation. Also, be aware that there seems to be some damage to the nipples, so be careful about that too.
