Why this material grade?
This product scored 76/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 87% Lyocell, 13% Polyester. Sustainability is scored separately as the Eco Rating. Blended from 87% Lyocell, 13% Polyester — 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. Lyocell (87%) is doing the heavy lifting. This is a smart buy.

87% Lyocell, 13% Polyester
Plastic-based — sheds microplastics in wash
Added Mar 30, 2026 · Data last updated Apr 1, 2026
Sustainability is scored separately — see the Eco Rating below.
🔬
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.
⚖️
Lyocell (score 80) is carrying this blend. Polyester (score 52) is pulling it down.

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.
