Hoodie Fabrics and Skin Safety: What You Need to Know

When we think of hoodies, we usually imagine comfort, warmth, and casual style. But behind the softness of your favorite hoodie lies a story about fabrics, finishes, and sometimes — hidden chemicals. In this post, we’ll walk through common hoodie materials, highlight a few harmful substances used in textile production, and explain how SAINIYA takes the right steps to make safer, skin-friendly hoodies.

What Are Hoodies Made Of?

Most hoodies today are made from:

• Cotton – a natural, breathable fiber known for comfort.

• Cotton–polyester blends – offering wrinkle resistance and durability.

• Functional synthetics – designed for performance, like quick-drying or water-repellent fabrics.

While these fabrics sound simple, the production process often involves dyes, coatings, and finishing agents. And that’s where potential risks for our skin come in.

Harmful Chemicals Found in Fabrics

Unfortunately, some conventional textile treatments may leave behind harmful substances. Here are two of the most concerning:

1. Azo Dyes

Used in up to 80% of textile dyes, these create vibrant colors. But certain types can break down into aromatic amines, which are linked to skin allergies and, in some cases, cancer risks (Allergy Standards, Wikipedia).

2. PFAS (“Forever Chemicals”)

PFAS are often applied as DWR (durable water-repellent) coatings to make hoodies resistant to water and stains. The problem? PFAS don’t break down easily in the environment, and they can accumulate in our bodies — with possible links to hormone disruption and cancer (Vogue Business).

Other substances worth noting:

• Heavy metals like lead and chromium (used in dyeing) can cause dermatitis and long-term toxicity (Earth Day).

• Formaldehyde-based resins (used in wrinkle-resistant finishes) may trigger skin irritation and are classified as potential carcinogens (Wikipedia).

SAINIYA’s Safer Approach

At SAINIYA, we believe comfort should never come at the cost of your health. That’s why we carefully control every step of our fabric process:

• ✅ Safe dyes only: We avoid carcinogenic azo dyes and instead use Oeko-Tex® or GOTS-certified alternatives.

• ✅ PFAS-free finishes: Our water-repellent hoodies are treated with fluorine-free technologies, avoiding “forever chemicals.”

• ✅ No heavy metals: We choose eco-certified dyes that exclude lead, chromium, and other toxic metals.

• ✅ Formaldehyde-free finishing: We eliminate wrinkle treatments that release formaldehyde, opting for cleaner, low-VOC methods.

The result? Hoodies that feel good, look good, and are kinder to both your skin and the planet.
