I hope someone can answer this - it says buy one size larger than normal, but it also gives a size chart with dimensions. Is the suggestion that one match oneself on the size chart, and then choose the next larger size? Or is it asking that we just choose the size up from our usual if we are not using the provided chart?
salkinGenerally with most items of clothing, I wear a small. I'm 5'9", 150 lbs, with a 38.5" chest measurement. This matches up perfectly with their medium. So I would think you buy the size that matches to your measurements. Careful with my suggestion though, as these are final sale.
