Sizing Instructions: So you get the right Dragynskyn shirt
Proper sizing for the fit that you desire is to understand that Dragynskyn is different as well as unique in apparel.
Dragynskyn is a 3 layer fabric that works optimally as a compression fit shirt. The size you would normally wear may be tighter fitting than what you would normally wear in an undershirt, so keep this in mind and consider what your needs are in a base layer.
For those that want a tighter fitting compression style shirt, choose a size similar to that you already wear in an undershirt.
For those that want or require a loser fitting shirt, choose a size or two larger to accommodate a larger frame, a more muscular body, anticipated weight gain, etc.
