Falls short on every axis — flimsy, synthetic-heavy, and rough on the environment.
Best for Skip if you have other options.

Why this material grade?
This product scored 52/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 100% Polyester. Sustainability is scored separately as the Eco Rating.
D (40-54): Below-average material composition — weak on durability or comfort.
Below average — 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.

🔬
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 Shirts: 100 expected wears.
× 0.60 for 110 g/m² (lightweight).
× 1.30 for Polyester (high-durability fiber, durability 85).
= 78 expected wears. $64 ÷ 78 ≈ 82¢/wear.
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, Biocide
- Antimony (trace): Virgin polyester contains trace antimony from PET production. Recycled polyester reduces but does not eliminate it.
- Biocide (likely): "Antimicrobial biocide" stated on the product page — observed, not inferred.

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.
