Composition

64% Cotton, 34% Nylon, 2% 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.
