This product scored 65/100 on the material-quality rubric (durability, comfort, breathability, warmth, moisture-wicking, care-ease), based on its composition of 63-70% Cotton, 28-35% Polyester, 2% Polyurethane. Sustainability is scored separately as the Eco Rating. Blended from 70% Cotton, 35% Polyester, 2% Spandex — the score is a weighted average based on each material's proportion.
C (55-69): Average material composition — typical blend, reasonable for everyday wear.
Average quality, high synthetic content
Decent for everyday wear, but the synthetic content means microplastic shedding and it won't biodegrade. Consider natural alternatives for your next purchase.

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.
