Why this material grade?

This product scored 71/100 on the 7-axis material rubric, based on its composition of 52% Hemp, 48% Cotton. Blended from 52% Hemp, 48% Cotton — the score is a weighted average based on each material's proportion.

B (70-84): Good material composition — above average across most axes.

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

52% Hemp, 48% Cotton

Good quality, eco-friendly

Solid fabric with strong environmental credentials. Hemp (52%) is doing the heavy lifting. This is a smart buy.

🌱

Cotton biodegrades in 1-5 months. When you're done with this, it returns to the earth — not the ocean.

🌿

Hemp requires 50% less water than cotton and needs no pesticides. It's one of the most sustainable fibers on the planet.
