Why this material grade?
This product scored 49/100 on the 7-axis material rubric, based on its composition of 63% Triacetate, 37% Polyester. Blended from 63% Acetate, 37% Polyester — the score is a weighted average based on each material's proportion.
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.
Breakdown
Composition
63% Triacetate, 37% Polyester
Plastic-based — sheds microplastics in wash
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 Jackets: 200 expected wears.
× 0.70 for Acetate (low-durability fiber, durability 50).
= 140 expected wears. $167 ÷ 140 ≈ $1.19/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.

Tradeoffs
Health Impact
Microplastic shedding · skin-contact synthetic load · likely chemical treatments
Low health impact — predominantly natural fibers with no major treatment flags.

Antimony
- Antimony (trace): Virgin polyester contains trace antimony from PET production. Recycled polyester reduces but does not eliminate it.
Biodegradability
Not BiodegradableMaterials will persist in the environment for decades.
Health & environmental impact →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.
