You shouldn't need to be a textile expert to buy comfortable clothes. But the way online shopping works today, you're basically buying blind. Fabric composition — the single most important factor in how clothes feel, last, and perform — is hidden away in tiny text you'd never normally check.

That's what a fabric composition checker solves. It makes the invisible visible.

The Problem: Hidden Information

Try this experiment: go to any fast fashion retailer and browse their dresses. Look at the product grid. Can you tell which ones are cotton and which are polyester? No. They all look the same in photos.

To find out what each dress is made of, you'd need to:

  1. Click into the product page
  2. Scroll past 5-10 photos
  3. Skip the description, sizing, and reviews
  4. Find the "Composition" or "Materials" section
  5. Read the tiny text
  6. Go back and repeat for the next item

For a page of 30 products, that's 30 click-scroll-read cycles. Nobody does this. So everyone buys polyester without knowing it.

The Solution: Fibr

Fibr is a free Chrome extension that checks fabric composition for you — automatically, visually, on every product.

When you browse a supported retailer (Zara, H&M, Mango, and more), Fibr reads the composition data and displays it as a colour-coded badge directly on the product image.

  • Green = 100% natural fibres (cotton, linen, silk, wool)
  • Yellow = Mixed (some natural, some synthetic)
  • Red = Mostly synthetic (polyester, nylon, acrylic)

Now you can scan an entire product grid and instantly see which items are made from quality natural fabrics and which are polyester-heavy — without clicking into a single product.

Why Fabric Composition Matters

Fabric composition isn't a niche concern. It directly affects:

Comfort

Natural fibres breathe, absorb moisture, and feel soft against skin. Polyester traps heat, repels sweat, and creates a clammy sensation. The "cheap" feeling of modern clothes is usually just polyester.

Odour

Bacteria cling to polyester 5x more than cotton. That's why synthetic shirts smell stale by lunchtime while cotton stays fresh. If body odour is a concern, fabric composition is the first thing to check.

Skin Health

Polyester and its chemical finishes are common triggers for skin irritation, heat rashes, and eczema flares. Dermatologists consistently recommend natural fibres for sensitive skin.

Durability

While polyester is technically "strong," it pills aggressively — those little bobbles that make clothes look old after a few washes. Cotton, linen, and wool maintain their appearance much longer with proper care.

Temperature Regulation

Natural fibres work with your body's temperature system. Polyester works against it. In summer, this is the difference between comfort and misery. In winter, it's the difference between warmth and cold-sweat clamminess.
