Why it's different: Reef Advantage Magnesium contains no ammonia. This is a common contaminant in every liquid magnesium supplement on the market. Severely depleted levels of magnesium (below 800 mg L) can cause depressed pH

This visor is nice & light-weight. I love the style & the tiny holes in front for breathability! I’m a huge Nike fan & appreciate the sturdiness, softness & comfort. It has a soft velcro adjustment, so it doesn’t scratch the back of your head, which is a plus. Value for the money is a little high, but well worth it since it’s my go-to hat for playing tennis, running or walking. Highly recommend this to others.
