Pros: 1) Like raglan sleeves 2) Price (although not constant so look around a bit) 3) Usually matte finish 4) Weight - neither too thin still too thick What would I change: 1) The material is not compatible. Russell makes them in different countries and the fabric varies from run to run. And it's not that the differences are "bad", it's just that some are less opaque than others, for example, and others are shinier, so you're never sure what you're getting, although often they are . expected with brands sold below premium prices. Just know, I just love the sizing, but if you want a more precise fit, you can size down.
