Why this material grade?

This product scored 48/100 on the 7-axis material rubric, based on its composition of 92% Polyester.

D (40-54): Below-average material composition β€” weak on durability or comfort.

Below average β€” consider alternatives

This fabric scores low on quality. It may pill, wear out quickly, or not feel great against skin. And when it does wear out, it'll sit in a landfill for decades. Look for higher-rated options.

Breakdown

Composition

92% Polyester

Plastic-based β€” sheds microplastics in wash

πŸ”¬

Every wash of synthetic fabric releases up to 700,000 microplastic fibers into waterways. Use a Guppyfriend bag to catch them.

🌍

This fabric will take 200+ years to decompose. That means a shirt you buy today will still exist in the year 2226.

⚠️

Synthetic fabrics can contain BPA, which mimics estrogen. Studies have found BPA transferring to skin through sweat contact.

Real life is messier than a formula: how often you wash, how you wash, whether you wear it inside-out, dry on low β€” all of it shifts the number. This is the ceiling under reasonable care.

High health impact β€” significant synthetic content or likely chemical treatments. For frequent skin-contact wear, consider a natural-fiber alternative.

PFAS, Antimony

  • PFAS (likely): 92% synthetic outerwear is typically treated with PFAS-based DWR (durable water repellent) for water resistance.
  • Antimony (trace): Virgin polyester contains trace antimony from PET production. Recycled polyester reduces but does not eliminate it.

What this score doesn't measure

  • Γ—Fiber grade. Staple length, micronaire, strength. "100% cotton" could be short-staple upland or long-staple Pima β€” same label, very different fabric.
  • Γ—Yarn processing. Singles count, ply (single vs two-ply), spinning method (open-end vs ring-spun vs compact), mercerization. Invisible from any label.
  • Γ—Knit / weave structure. Single jersey vs interlock, knit tightness. A loose knit pills; a tight knit lasts.
  • Γ—Fabric weight (GSM). One construction signal among several β€” and high GSM can come from loose cheap yarn just as easily as from fine tight yarn. We have it for blank manufacturers, rarely for retail.
  • Γ—Pre-shrink processing. Sanforized cotton shrinks ~1%; non-sanforized can shrink up to 10%. Not visible from the composition tag.
  • Γ—Construction quality. Stitch density (SPI), seam types, collar geometry, manufacturing tolerances (AQL). These often matter more than the fiber itself.
  • Γ—Specific chemical loads. Health Impact flags "likely PFAS / possible formaldehyde" from composition Γ— category β€” we don't lab-test individual SKUs.

We rate the fabric, not the garment. Composition is the floor of what you're guaranteed to be getting β€” most shoppers don't have that.
