This cool design is ideal for the portable music generation. This design features light-up graphic equalizers that are sewn right onto the shirt and actually will bounce up and down to music or other sound sources. The super-thin flexible EQ design feels somewhat like a thick iron-on transfer.

Each 100% cotton t-shirt has a hidden sewn-in pocket for the small control unit. Features a variable sensitivity dial to customize the level of reactivity to sound volume. Uses 4 replaceable AAA batteries. The shirt is hand-washable (just remove the cables & driver) and comes in adult sizes Small through XXL plus 5XL. (XXL has a $3.00 size surcharge, 5XL has a $4.00 size surcharge.) The sewn-on design itself is about 8" wide by 5 1/2" high.
