    Great fitting workout shirt

    These are very comfortable and versatile shirts for various exercises. Plenty of room to move while wicking off sweat.

    Not a fan of the 100% polyester

    I won't stop wearing it, just prefer a shirt with cotton. My favorite fitting from another supplier is 75% cotton, 20% polyester, 5% spandex. Will try the Origin Core t-shirt next purchase,
