This is from an Australian Product Alert email. It's a new special edition Cool Racerback and the web page is labeled "Scrunch." I'm not sure what is going on in the back but it looks like the back and maybe the entire bottom portion of the tank is made of sheer luon. I wish they provided a full length shot of the back but I think it has promise if part of the tank is made of sheer luon. It would be heaven for hot days and hot workouts. If an Aussie readers have seen this tank and can give us more details on what it looks like we'd be happy to hear.
