Why this material grade?
This product scored 73/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 100% Wool. Sustainability is scored separately as the Eco Rating.
B (70-84): Good material composition — above average across most axes.
Good quality, eco-friendly
Solid fabric with strong environmental credentials. Wool (100%) is doing the heavy lifting. This is a smart buy.
Premium fabric, premium price
$636Better-than-typical fabric, but priced above the category median.

Fabric value only — compares material quality to price vs other jackets. Construction, fit, and brand aren't measured.

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 Jackets: 200 expected wears.
× 1.00 for Wool (mid-durability fiber, durability 70).
= 200 expected wears. $636 ÷ 200 ≈ $3.18/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.

Label Confidence
LOWLabel confidence low — multiple signals suggest the composition may be incomplete, vague, or hard to verify. Treat scores as directional.
- ⚠"100% Wool" claim on a jackets item is unusual — outerwear typically has synthetic linings, padding, or DWR coatings that should be disclosed.
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.
