PFAS are a group of chemicals that have received increased attention from regulators, consumers, and health organizations. CastleFlexx tests because material transparency matters, especially for products people may use regularly against the body. The tested CastleFlexx sample showed Total Organic Fluorine (TOF): Not Detected at the reporting limit shown in the Eurofins report.

Regular exercise equipment is exposed to sweat, moisture, and frequent handling, creating conditions where microorganisms can grow over time. Antimicrobial testing helps verify that the fabric is designed to resist the growth of certain odor-causing microbes on its surface.

The SGS REACH SVHC Screening is an independent laboratory test that analyzes products for the presence of chemicals classified by the European Chemicals Agency (ECHA) as Substances of Very High Concern (SVHCs).

CastlePack was screened for 253 officially listed SVHCs plus one additional potential SVHC, covering many commonly discussed chemical groups such as PFAS-related compounds, phthalates, lead, and BPA-related substances. The laboratory found no tested SVHCs above the reporting threshold of 0.1% by weight, resulting in a PASS.

Independent PFAS testing helps verify that product materials have been screened for a broad range of regulated PFAS compounds. It also supports compliance with evolving global chemical regulations while giving customers greater confidence in the materials used.

For this test, SGS analyzed the CastleAir sample using advanced laboratory techniques, including GC-MS, GC-MS/MS, and HPLC-MS/MS, to screen for a comprehensive list of regulated PFAS compounds and PFAS-related substances. The results reported no detectable levels of the tested PFAS compounds above the applicable limits, resulting in a PASS.
