Love C-IN2 tanks. I had
Love C-IN2 tanks. I had the original CORE version which is not made anymore. It's now called "Layers" which is the same fit. I originally purchased an XL in 2016. The fit is pretty much the same. I have a very athletic physique and recently purchased the size M which is fine but a smidgen shorter. I went ahead and purchased size L which seems to be the right fit. It's really the length that is the difference. Happy Shopping!
