The material provides firm support and stays locked in place during high-impact movement, making it ideal if you prefer a streamlined silhouette without any bunching. However, because the fit is so snug, it leaves very little room for stretch or layering underneath. If you fall between sizes or prefer a slightly more forgiving, breathable feel around your neck and shoulders, this size may feel a bit restrictive compared to the XS. For anyone seeking maximum compression and a true-to-smallest fit, 0XXS delivers exactly that.
