Replace your cotton tee or any petroleum-based poly to feel the health benefit and function of the I/O Bio Merino Universal Tee. Whatever your activity may be, the looser I/O fit enhances breathability and enables quick drying while wearing. It may only be a t-shirt, but you'll wear it for 20 years and covet the feeling each time you put it on.
