Design me a Product

Hi, My husband is a tiler and he has an idea to create a t-shirt with a dust mask incorporated in it. He came up with this idea because he needs to use his dust mask several times during the day but not for a very long time. Every time when he needs to cut a tile, he puts on his dust mask. This is time consuming because you must have it close to you all the time so instead of using his dust mask, he ends up using his T-shirt. Just pulling his T-shirt over his nose until he makes the cut. He noticed some T-shirts filter the dust better than other so he thinks why not having a T-shirt with a dust mask incorporated at the base of the collar. The mask must be part of the T-shirt not just [login to view URL] with a rolled neck are already on the market (look at this website) [login to view URL] so we needed a different design. What we need to further develop is this idea [login to view URL] The front part of the t-shirt must be design in a way which allows just to be pulled over the nose, having a dust filter incorporate in it and perform as a dust mask and in the same time looks nice. The design should not include a hood, rolled neck or zip. If you have any creative ideas for this project just let us know.
