Quite simply, your 2XU Compression garment should snugly and firmly
fit the body. It should not, however, ‘cut in’ to any part of the body. If
this is the case, your compression garment is not fitted properly and
you should review your size choice. For upper body garments, a free
range of movement of the shoulders is essential, as is comfort in the
underarm area.
For specific sizing, please refer to our size chart at
www.2xu.com/popup/sizechart-comp.html, taking into consideration
that if you are near the borderline for sizes or you wish to wear your
compression garment primarily for recovery purposes, you should
choose the smaller size if comfortable.
