Ensure you are not using fabric softeners during wash cycles, as these coat fibers and reduce garment performance.

Visible wear or loose threads

Check that the garment is not being dried on high heat settings, which can break down synthetic elastic components.

Setup, Compatibility & Care

To ensure the longevity of your compression gear, proper care is essential. Always wash the garment in cold water with like colors. Do not use fabric softeners, as these can degrade the moisture-wicking properties of the synthetic fibers. Use only non-chlorine bleach if necessary and tumble dry on a low setting. Do not iron or dry clean the item, as high heat can damage the elastane content and compromise the compression fit. Before your first use, consider writing your initials on the designated neck locker tag for easy identification in shared environments.
