Definite Articles Sustainability Profile

Definite Articles presents itself as an activewear brand focused on chemical safety and lower long-term pollution. It says its finished garments are independently tested for PFAS, BPA, and 50+ other chemicals of concern, and that it avoids performance chemical treatments on its synthetics. The brand also uses CiCLO® technology, which is meant to help synthetic fibers break down faster when discarded. It is a Certified B Corporation, which means it has been checked against a wider social and environmental standard. The public picture is mixed: the brand has strong self-reported sustainability claims, but third-party customer reviews are poor on Trustpilot for one related domain.

Positive Sentiment Found
Public sentiment in the available material is limited, but the brand does have some strong third-party signals. Definite Articles is listed as a Certified B Corporation on B Lab’s directory, which means it has been assessed against a recognized framework for social and environmental performance, accountability, and transparency. The brand also appears in customer-facing sustainability discussions through Commons, a values-based shopping app that highlights expert-rated brands. On the brand’s own site, it points to independent testing by Intertek and to a tree-planting partnership with One Tree Planted, which may support trust for shoppers looking for more detail on materials and testing. However, these are mostly brand claims rather than outside reviews of the sustainability program itself.

Common Criticisms:
The clearest negative signal is from Trustpilot, where the related domain definiten.com has a 1.4 out of 5 rating based on 41 reviews. That is a very low score and suggests unhappy customers, although the snippet does not say whether the complaints are about sustainability or general service. A second Trustpilot result for definiteg.com shows 2.5 out of 5 from 6 reviews, which is also weak but based on a very small sample. There is no independent sustainability audit in the material beyond the B Corp listing, and the brand’s own claims about chemical safety and biodegradability are not backed here by outside test reports. That means some claims remain unverified in the public material shown.
