 Reduce harmful ammonia & nitrites faster
 Lower maintenance by stabilizing water quality

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.
