Brand Questions

How does ONDU choose which brands to feature?

ONDU selects brands through a rigorous vetting process focused on fabric composition, transparency, and ethical practices. The most important criterion is that a brand offers products made primarily from natural or plant-based fibers. We review the fiber content of every product and look for brands that consistently use materials like merino wool, Tencel, organic cotton, hemp, silk, and alpaca rather than relying on polyester or nylon as a base.

Beyond materials, we evaluate each brand's commitment to transparency. This includes publishing fiber content details, sourcing information, and manufacturing locations. We look for third-party certifications such as GOTS, OEKO-TEX, B Corp, and bluesign as indicators of verified standards. Brands that provide vague or misleading fabric claims are not featured on our platform.

We also consider product quality, brand reputation, and customer feedback. Our goal is to curate a collection that represents the best available options across activewear, loungewear, sleepwear, and bedding. Currently featured brands include Reprise Activewear, Organic Basics, Icebreaker, Pangaia, Mate the Label, and many more.

Why

Natural temperature regulation. Antibacterial. Odor resistant. Moisture wicking without plastic.
