The Bio Silk Tee is a loose fit performance tee. It survives the test of time through sports and breathability. I ran with it in the desert in Mexico and it was the perfect weight. Made from the Evo by Fulgar yarn, this is a bio-based fabric, sourced from an Italian mill.

Made with an ultra light weight, breathable, super stretch, quick dry, natural bacteriostatic properties.

A loose fit, this can easily be used for a long run, a sweaty hike, or even just to wear in the comfort of your home.
