This product scored 70/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 83% Wool, 12% Polyamide, 5% Elastane. Sustainability is scored separately as the Eco Rating. Blended from 83% Wool, 12% 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.

Well-balanced fabric that should serve you well. The natural-synthetic blend offers durability with comfort. Follow the care guide to maximize lifespan.
Below-typical fabric quality at an above-median price — you may be paying for the label, not the material.
Fabric value only — compares material quality to price vs other underwear. Construction, fit, and brand aren't measured.

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.
Reasonable cost-per-wear
Base for Underwear: 80 expected wears.
× 1.00 for Wool (mid-durability fiber, durability 72).
= 80 expected wears. $55 ÷ 80 ≈ 69¢/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.
