If you are a Portal fan and really into the cosplay scene, then we have the perfect piece to add to your costume.
Check out this Aperture Science Gas Mask from the Portal game, made by TwoHornsUnited. This is a custom made mask, and you can get your hands on one for $280! Now that is a VERY high price, but it looks to be a high quality piece.
They are taking orders now and making a waiting list. So if you want one, you better act right now and head over to their DeviantArt page.
