A comfortable compression.
XL fits the Best - Measurements: 37” Ribs 43” Chest. I have a large chest and this helped knock down the appearance while making it so I can still breathe and live my life. I can exercise and work out in this without feeling like my lungs are collapsing. I definitely could not size down comfortably to get flatter. XL did the best to actually reduce the appearance of my chest. Getting it back off was a bit of a struggle, but the 2x was too big to actually reduce my chest. It does the job, and like any compression garment, you feel the compression, but not in a way that made me feel claustrophobic.
