Why this material grade?

This product scored 64/100 on the 7-axis material rubric, based on its composition of 90% Cotton, 10% Polyester Slim Fit With. Blended from 90% Cotton, 10% 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.

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

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.

🔬

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.

⚠️

Synthetic fabrics can contain BPA, which mimics estrogen. Studies have found BPA transferring to skin through sweat contact.
