GOREWEAR M Base Layer Sleeveless Shirt

Description says women’s but it’s men’s or unisex. Works well for cycling and is correct size for me. Gore cycling kit is always a bit expensive but just works so is worth it in the end.

It's a very slim fit though, so glad I ordered a large as I want to wear this over my tops when I have my jacket open and just want a bit more protection on my chest without feeling too warm.
