Thanks for asking, John! The CURAD 15–20 mmHg Compression Hosiery line (such as the standard nylon and spandex variants) is typically constructed with an 80% nylon and 20% spandex blend to deliver durable graduated compression and a flexible, comfortable fit.
(Note: Exact percentage breakdowns can occasionally vary depending on the specific product sub-line, style, or manufacturing batch—such as cushioned variants—so checking the product packaging label is always recommended if precise compliance tracking is required).
Thanks,
