The first synthetic-blend running shirt that biodegrades like a 100% cotton tee, our Runterra Bio offers the enhanced moisture and odour control of specially-formulated 37.5® polyester with the comfort and versatility of cotton. It's new, innovative fabric breaks down into organic compounds in under four years. Conventional polyester takes four hundred.

Don’t sweat it — this tee will only start to biodegrade in anaerobic (oxygen-poor) environments. It breaks down in the landfill, not in your closet.

As an added bonus, Janji donates 2% of all sales to clean water initiatives worldwide.
