Nowadays, you can get wifi access nearly everywhere - but there are still some places left where there is no wifi available. That's why it's a very important information if there is wifi available. The information is so important that also the people around you should be aware of it - now you can tell them using this Wifi Shirt:

The display is realised by a soft plastic frame, which is fixed to the shirt using a hook-and-loop fastener. It is powered by a battery box, which is carried in a pocket inside the shirt (see additional pics). You can switch the effect off and you need 4 AAA batteries, which are not included. The shirt is made out of 100% cotton, black and it is hand wash only (for which you can remove the battery pack).

Here are the sizes of the shirt in cm. The first number indicates the width directly under the arms (B) and the second number indicates the height (H) (see also the illustrating picture):
M: 52cm / 67cm
L: 55cm / 72cm
XL: 57cm / 74cm
