Learn about the recycled fabric composition and sizing of the Protect the Sea T-Shirt from Klean Kanteen Apparel.
Quick answer
The Protect the Sea T-Shirt is made from 100% recycled materials — upcycled cotton and recycled plastic bottles — and comes in standard unisex sizing. All sales are final, so choosing the right size matters.
Why recycled fabric matters
This shirt uses upcycled cotton and recycled plastic bottles, turning waste into a soft, easy-wearing garment. The environmental benefit is clear: less plastic in the ocean and less virgin cotton grown. The tradeoff is that recycled blends can sometimes feel slightly different from 100% conventional cotton, but the fabric here is designed for everyday comfort.
No returns or exchanges
Klean Kanteen notes that all clothing sales are final — no returns or exchanges. This makes it essential to check the size chart before ordering. If you are between sizes, consider sizing up for a more relaxed fit, as recycled blends may have less stretch than some synthetic blends.
