Why this material grade?

C (55-69): Average material composition — typical blend, reasonable for everyday wear.
Everyday quality
This fabric does the job for daily wear. Not premium, not bad — it's the middle of the road. At least it's easy to care for.
Breakdown
Composition
100% Cotton
All-natural fiber
Cotton biodegrades in 1-5 months. When you're done with this, it returns to the earth — not the ocean.

How we got there
Base for Shirts: 100 expected wears.
× 0.70 for Cotton (low-durability fiber, durability 60).
= 70 expected wears. $34 ÷ 70 ≈ 49¢/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.
