Why this material grade?
This product scored 82/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 83% Merino Wool, 12% Recycled Nylon, 5% Spandex. Sustainability is scored separately as the Eco Rating. Blended from 83% Merino Wool, 12% Recycled Nylon, 5% Spandex — 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. Merino Wool (83%) is doing the heavy lifting. This is a smart buy.

Sustainability is scored separately — see the Eco Rating below.
⚠️
Synthetic fabrics can contain BPA, which mimics estrogen. Studies have found BPA transferring to skin through sweat contact.
🌍
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.

How we got there
Base for this category: 100 expected wears.
× 0.85 for 170 g/m² (mid-weight).
× 1.00 for Merino Wool (mid-durability fiber, durability 73).
= 85 expected wears. $36 ÷ 85 ≈ 42¢/wear.
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.

Label Confidence
MODERATELabel confidence moderate — one signal suggests the composition may be incomplete or under-verified.
- ⚠Recycled-fiber claim without explicit certification (GRS, RCS). Chain-of-custody for recycled materials is hard to verify without one.
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.
