NavyOaks works with a wide variety of brands and vendors so we do not have a generic sizing chart.  The being said, we always thoroughly inspect and test sizing on each item that comes in to our warehouse.  If an item runs smaller or larger than standard fit, we will always be sure to note it in the description.  If you have any other questions on sizing or fitting, please reach out through the Get in Touch tab! Happy Shopping and thank you for your continued support!
