Why this material grade?
This product scored 63/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 51% Wool, 49% Polyester. Sustainability is scored separately as the Eco Rating. Blended from 51% Wool, 49% Polyester — the score is a weighted average based on each material's proportion.
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.
Great fabric value
$139Better-than-typical fabric for this category, at a below-median price.
Fabric value only — compares material quality to price vs other pants. Construction, fit, and brand aren't measured.

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.
Wool is naturally antibacterial and self-cleaning. You can air it out between wears instead of washing — it'll stay fresh.

How we got there
Base for Pants: 200 expected wears.
× 1.00 for Wool (mid-durability fiber, durability 77).
= 200 expected wears. $139 ÷ 200 ≈ 70¢/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
Moderate health impact — some synthetic content or possible chemical treatments. Rotate with natural-fiber alternatives where you can.

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.
