Why this grade?
This product scored 62/100 based on its composition of 100% Recycled Polyester Backershell Has.
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.
Every wash of synthetic fabric releases up to 700,000 microplastic fibers into waterways. Use a Guppyfriend bag to catch them.
This fabric will take 200+ years to decompose. That means a shirt you buy today will still exist in the year 2226.
Synthetic fabrics can contain BPA, which mimics estrogen. Studies have found BPA transferring to skin through sweat contact.
Biodegradability
Not BiodegradableMaterials will persist in the environment for decades.
