Why this material grade?

This product scored 71/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 53% Hemp, 47% Cotton. Sustainability is scored separately as the Eco Rating. Blended from 53% Hemp, 47% Cotton — the score is a weighted average based on each material's proportion.

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

Good quality, eco-friendly

Solid fabric with strong environmental credentials. Hemp (53%) 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.

How we got there

Base for Shirts: 100 expected wears.

× 1.00 for Hemp (mid-durability fiber, durability 76).

= 100 expected wears. $84 ÷ 10084¢/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.
