Worn once Like new Size small Purple 2 in one short 1 pair of shorts. 2 layers. All the possibilities. The Vital Seamless 2.0 2-in-1 Shorts feature an inner layer made from the classic seamless, sweat-wicking fabric in the rest of the Vital Seamless collection. Then, we’ve added an extra layer made from a brand new, lightweight fabric for better breathability in those high sweat sessions. And, thanks to the looser fit of the outer layer, you get a little extra coverage when you want it. Because you can do it all, and so can Vital.
