Why this material grade?

This product scored 65/100 on the 7-axis material rubric, based on its composition of 97% Cotton, 3% Elastane. Blended from 97% Cotton, 3% Spandex — the score is a weighted average based on each material's proportion.

C (55-69): Average material composition — typical blend, reasonable for everyday wear.

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.

Composition

97% Cotton, 3% Elastane

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.

🌍

This fabric will take 200+ years to decompose. That means a shirt you buy today will still exist in the year 2226.

🧺

Dryer heat destroys spandex/elastane over time. Your leggings and stretchy clothes will last 2x longer if you skip the dryer.
