Why this material grade?
This product scored 70/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 70% Organic Cotton, 30% Recycled Polyester. Sustainability is scored separately as the Eco Rating. Blended from 70% Organic Cotton, 30% Recycled Polyester — the score is a weighted average based on each material's proportion.
B (70-84): Good material composition — above average across most axes.
Good quality, eco-friendly
Solid fabric with strong environmental credentials. Organic Cotton (70%) is doing the heavy lifting. This is a smart buy.
Great fabric value
$60Better-than-typical fabric for this category, at a below-median price.

Sustainability is scored separately — see the Eco Rating below.
🔬
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 Sweaters: 100 expected wears.
× 1.50 for 320 g/m² (premium heavyweight).
× 1.00 for Organic Cotton (mid-durability fiber, durability 67).
= 150 expected wears. $60 ÷ 150 ≈ 40¢/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.

Chemicals LOW
No flags
30% synthetic content (recycled polyester). Moderate microplastic shedding — a washing bag catches 86% of fibers. Counter-intuitively, recycled polyester is not cleaner here: mechanically recycled PET fibers are shorter and more brittle, so they can shed as much as — or more than — virgin polyester. The recycled label improves sustainability, not microplastic shedding.
Biodegradability
Not BiodegradableMaterials will persist in the environment for decades.
Label Confidence
LOWLabel confidence low — multiple signals suggest the composition may be incomplete, vague, or hard to verify. Treat scores as directional.
- ⚠Organic cotton claim without explicit certification (GOTS, OCS). Check brand's certification disclosures separately.
- ⚠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.
