This product is also Uni-Sex. Size chart recommendations provide a loose and baggy fit, therefore sizes run big. Women can push the height limits as displayed on the size chart by 1-2 inches because our products are unisex and men need more room in the crotch. For females between sizes we recommend sizing down. For males between sizes we recommend sizing up.
