Why this material grade?
This product scored 76/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 100% Linen. 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. Linen (100%) is doing the heavy lifting. This is a smart buy.
Premium fabric, premium price
$300Better-than-typical fabric, but priced above the category median.
$3.95 per quality point Category median: $95 · grade C
Fabric value only — compares material quality to price vs other shirts. Construction, fit, and brand aren't measured.

Linen is made from flax, which grows in poor soil with little water. It's been used for clothing for over 30,000 years.

How we got there
Base for Shirts: 100 expected wears.
× 1.30 for Linen (high-durability fiber, durability 80).
= 130 expected wears. $300 ÷ 130 ≈ $2.31/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.

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.
