neck pillow hood / neck pillow hood

I designed neck pillow in hooded T-shirts.
The instruction is simple, which is created through various experiments.
If you want to rest , blow air in the tube which is connected to the hooded T-shirt.
After using it, you can let the air out from the tube following the same way.
Besides, you can use it without wearing the hood.
Anyone who pursues convenience like travelers, students, drivers, workers, and etc., can easily take advantage of this neck pillows in the hooded T-shirts.
