If you don't know, you don't know; hell we don't even know how the invisibility works on this stuff but we think it's kind of like a chameleon you just start to blend in with everything.

I like it very much because the comfort and the design are good. Also, if there is a chance, I want to buy it by all means.
Love my singlet. Fits snug in a good way. Thank you.
