But most of us never compare the one thing that touches our skin for hours every day: what the fabric was treated with.

A sheet set, a towel, or a pair of joggers can look identical on two product pages. One is cotton and plant color. The other is cotton plus a finish you will never see listed. The price tag tells you the discount. The label rarely tells you the rest.

Why this matters more this year

Regulators are starting to look at the same blind spot.

PFAS, often called forever chemicals, have been used in textiles for water, oil and stain repellency. Since January 2026, France has banned PFAS in consumer clothing and footwear, with some exemptions. On 10 October 2026, a new EU limit on one type of PFAS (PFHxA) started applying to clothing, and it extends to all other textiles in October 2027. In the US, Maine and Vermont now restrict textiles with intentionally added PFAS.

Here is the detail most shoppers miss. These rules generally apply to products placed on the market after the deadline. The EU rule, for example, does not apply to products already on the market before its start date. Some of what gets cleared out at a discount may simply be older stock.

That does not mean a sale item is unsafe. It means the label alone cannot tell you.

The six-point check

1. 1

   Read the performance words as ingredient words.

   "Wrinkle-free", "non-iron", "stain-resistant" and "water-repellent" describe a finish, not the fiber. The US Government Accountability Office notes that formaldehyde-based resins are used to enhance wrinkle resistance, especially in cotton. Easy care usually comes from something added.

2. 2

   Look for a third-party certificate, then look it up.

   A logo is a claim. A certificate number is proof you can check. OEKO-TEX Standard 100, for example, has banned the intentional use of PFAS in certified textiles since 2023. GOTS covers organic fiber and how it is processed. If a brand shows a badge but no number, ask for it.

3. 3

   Ask where the color comes from.

   Color is the largest ingredient most labels leave out. "100% cotton" tells you the fiber, not the dye. A brand that knows its dyes will name them.

4. 4

   Check every material, not just the main one.

   The headline fiber is only part of the product. Elastic, thread, trims and blends count too. Good brands list them, even when the answer is less tidy.

5. 5

   Be wary of words that sound good but say nothing.

   "Eco", "green" and "conscious" are easy to print and hard to check. Since 27 September 2026, the EU has banned generic environmental claims like these unless they are backed by recognised proof. Specific beats vague, every time.

6. 6

   See if the brand will show you the whole journey.

   Where was the cotton grown? Where was it dyed and sewn? Who tested it? A brand that answers those questions in public has nothing to hide in private.

How we approach it at AIZOME

We built our process around these questions, first for bedding, and now across our whole line: sheets and duvet covers, towels, bathrobes, loungewear and socks.

Our organic cotton is grown in the Söke Valley in Turkey. Our colors come from plants such as indigo, madder root and sumac. Our textiles are GOTS certified and tested to OEKO-TEX Standard 100, and our Seed-to-Sheet™ page shows the journey from field to finished product, with test results.

Everything we make is PFAS-free. Our process uses organic cotton, plant dyes, water and ultrasound, and the one finishing agent we use is bluesign® approved; bluesign bans the use of PFAS in the chemicals it approves. We didn't just take that on trust. In July 2025, TÜV SÜD tested our core bedding against the EN 17681-1:2025 PFAS method, covering PFOS, PFOA, PFHxA, PFHxS and other regulated PFAS. Every sample passed.

We also try to be honest about the exceptions. Our new socks contain natural latex, because without it they would not stay up. You will find that on the label, not in the small print.

That is also why we created the Textile Health Facts label: a simple panel that shows what is in a textile, the way food labels do.
