SIZING Jockmail underwear uses Asian sizes and runs smaller than standard US sizes. DoNOT>order your "normal" size underwear. We also don't recommend ordering your regular jeans size. Jockmail is low-rise and sits on your hips and not your true waist. Instead, measure your body around your hip bones and consult the chart below for correct sizing. If you cannot measure yourself, we recommend ordering two full sizes up from your regular underwear size. If you have bigger thighs, we recommend choosing the jockstrap or brief models, as the legs can also be tight. Alternatively, check out our Cake Bandit line, which comes in standard US sizes and goes up to 3XL. MEDIUM - 27-29" LARGE - 30-32" EXTRA LARGE - 33-35" XXL - 36-38" CARE INSTRUCTIONS Protect your packer gear by washing it in cold water. Drying this product in the dryer will result in normal cotton shrinkage. If you'd like to minimize this, your Jockmail underwear can be air-dried.
