Pure Invisible is a clear liquid-gel roll-on anti-perspirant that claims 'invisible protection, no white marks.'

I found it to live up to it's claim, as long as you have time to apply and let dry. Due to the consistency of the product, it goes on wet and requires some drying time before you put your clothes on over top. It is a little annoying to stand with arms akimbo waiting for your underarms to dry, but for certain tank and strapless tops, I find this is a good way to avoid unsightly white marks or worse those little balls of deodorant that can form from over application.

Not an everyday anti-perspiration, but great for special occasions.
