This idea came to me, last year when the launch of Pokemon Go came out. It is a T-Shirt Vest with Pockets durable to handle the weight of power banks i.e (portable chargers). This will of course have who ever plays that are on any of the three teams colours with team emblem on it. As well who does have a team, will have just Pokemon Go on it with Team Neutral on it.
This benefits the players who have it multiple charger carrying them in there back pack, to have they're power bank on them without having to take they're bag off and pulling them out.
Summer is right around the corner and these t-shirt vest will be comfortable to wear, as well the market for this will increase with the launch of the Legendary Pokemon as well make the game much more enjoyable for those whom play the game.
