Why this grade?

This product scored 57/100 based on its composition of 69% Nylon, 31% Spandex. Blended from 69% Nylon, 31% Spandex — the overall score is a weighted average based on each material's proportion.

C (55-69): Average — typical blend, reasonable for everyday wear.

Composition

69% Nylon, 31% Spandex

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.

⚠️

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.
