Recently posted on the Park City Facebook page, the Run: Weightless Singlet. I am intrigued by the weightless part. As soon as I find out more and sport more photos I will update this post. The Lulumum blog says this is made of luxtreme but it's hard to tell from the photo. I might have to trade in my luxtreme Deep Breath for this. I do like luxtreme Singlets a lot and it looks like I won't have to worry about over exposure in this tank.
