Outdoor activities seem to be synonymous with summer. The grass is green, the sky is blue, and you can’t help but want to run and play. If your version of fun is something along the lines of baseball or soccer, then you’re going to need a little bit of structure with how your team faces another. You want to write down your plays so your teammates know what’s going on, but you don’t want it to be out for the whole world to see.

The Zipboard will give you the ability to write down and erase plays, as well as keep them from wandering eyes. It’s a retractable white erase board that is 17×12″. While it’s not particularly large, you don’t need something huge to put down an ‘x’ here and an ‘o’ there. Simply pull out the board and it will be rigid, and at the push of a button, it will retract back into a slim tube that can either go into your pocket or clip on to your belt. It’ll cost you around $41, but would be rather useful for any team that needs a little help getting coordinated.
