Why this material grade?

This product scored 62/100 on the 7-axis material rubric, based on its composition of 100% Recycled Polyester.

C (55-69): Average material composition — typical blend, reasonable for everyday wear.

Average quality, high synthetic content

Decent for everyday wear, but the synthetic content means microplastic shedding and it won't biodegrade. Consider natural alternatives for your next purchase.

Breakdown

Composition

100% Recycled Polyester

Plastic-based, recycled — sheds microplastics in wash

Fabric details
eVent™Fair Trade Certified™
Mesh construction
🔬

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.

How we got there

Base for Accessories: 200 expected wears.

× 1.30 for Recycled Polyester (high-durability fiber, durability 83).

= 260 expected wears. $90 ÷ 26035¢/wear.

Missing GSM — this is a category-level estimate, not garment-specific. Expect ±30% variance.

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

Antimony

  • Antimony (trace): Recycled polyester carries reduced (but non-zero) antimony residue from upstream PET feedstock.

Label Confidence

MODERATE

Label confidence moderate — one signal suggests the composition may be incomplete or under-verified.

  • Recycled-fiber claim without explicit certification (GRS, RCS). Chain-of-custody for recycled materials is hard to verify without one.

What this score doesn't measure

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