You'll never lose sight of the game plan when you've got a NIKE® Evo Control playcoach by your side. Designed to be worn on your wrist or belt, it features 3 large windows for easy viewing when you have mere seconds to call the perfect play. The Dri-FIT® fabric sleeve also acts as sweatband by wicking away moisture to keep your arm cool and dry as the competition on the field heats up.
My Boys are starting with their 12U football and this product works great for our team; a few other teammates have this product. we run a no huddle offense and me as a coach just need to call a number and our team knows which play to execute.
One minor note: When the boys get sweaty or accidently spill water on the product, precipitation gets in on the paper inside. Recommend moving the slits from the end of the armband to the fold of the armband flap. This may seal better so precipitation doesn't get between the plastic slits.
