Its underwear uses a blend of 53% hemp, 44% organic cotton and 3% spandex with dyes it says are OEKO-TEX certified, and is made in a factory in China the brand describes as BSCI-audited, which it audits through a team member based on the ground.

It is a PETA-Approved Vegan and Green America Certified brand.

Rating Summary

Nature & Animals

The fabric is mostly hemp and organic cotton, both low-impact fibres, with dyes it describes as OEKO-TEX certified and non-toxic, and a small share of spandex.

Hemp needs little water or pesticide.

The brand publishes less about its climate footprint, water tracking, packaging beyond recycled mailers, and end-of-life recycling, which is where most of its headroom sits.

Communities & Wellbeing

The underwear is made in a BSCI-certified factory that the brand says provides fair wages and safe conditions, and WAMA keeps a team member in China to audit the factory and manage the relationship directly.

Values & Governance

WAMA is a founder-owned independent business and a Green America Certified Business that discloses its fabric composition, certifications and manufacturing arrangement.

It does not yet publish a formal sustainability report or a charitable-giving programme.

Product Performance

Independent reviews are strongly positive, praising the underwear as durable, comfortable, breathable and naturally anti-odour, and the brand offers a first-pair guarantee.

The thicker hemp fabric is a matter of preference.

From public information

Our indicative assessment places WAMA in our Changing tier, based on the brand’s public disclosures. Changing is our fourth tier, for brands scoring in the top 60% of the brands we have rated within their category. Learn more about our ratings.

This initial rating was assessed on 9 July 2026 from public information, using wamaunderwear.com, its certifications, and independent reviews. Certifications shown were checked against the issuing bodies' public registries in July 2026. Third-party audits such as BSCI keep no public registry and are shown as the brand reports them, not independently verified. Initial ratings apply our standard 22-criteria methodology to published evidence only.

Brands typically score higher in a full rating because they can evidence more. Learn more about our scoring.

Is this your brand?

This initial rating is based on information that WAMA has made public. Our full rating lets brands evidence more and generally receive a higher rating. For WAMA, that could include a climate footprint or reduction disclosure, a full restricted substances list or whole-product certification, a take-back or end-of-life path, water data for its hemp and organic cotton, a plastic-free packaging specification, and a donation programme.

A full rating also unlocks your brand’s tier badge here and in every guide that features you. It also includes a badge licence for your own site. There is a fee for a full rating. The process takes a couple of weeks and about two hours of your team’s time.

"The whole process was authentic and I felt that you held me accountable for our claims."
