About Therafirm


For over 50 years, Therafirm has been a leader in manufacturing healthy, gradient compression products. Knit-Rite, Inc. purchased Therafirm in 2000 and has re-invented the brand & product with updated colors, new styles and high quality standards.


Therafirm products are quality inspected, ensuring superior, true gradient compression garments. Products endure constant evaluation and adjustment to meet quality standards and customers' needs. Therafirm has a certified quality system, receiving ISO 13485 certification.


Therafirm has evolved under new ownership through innovation, adding four new lines of product since 2000 including Core-Spun, TherafirmLight, Preggers and GOGO. With our roots in the medical field, all products are developed with consumer's health top of mind. Some products claiming to offer "compression" are not true gradient compression products and may contain little to no compression or actually offer reverse compression. Therafirm's unique ability to combine healthy, true gradient compression with the most up-to-date technologies available results in superior, quality compression garments.

Made in the USA

Therafirm products are proudly made in the USA in our own manufacturing facility in Hamlet, NC with corporate headquarters in Kansas City, KS.
