Why this grade?
This product scored 55/100 based on its composition of 75% Rayon, 25% Nylon. Blended from 75% Rayon, 25% Nylon — the overall score is a weighted average based on each material's proportion.
C (55-69): Average — 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.
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.
The fashion industry produces 10% of global carbon emissions — more than aviation and shipping combined.
Biodegradability
