The athlete's body gets shaped and honed over time, and so do her clothes. The most versatile of our Regulator\\" tops, the R2 has taKeQ on a more streamlined and sculpted fit this year; we also raised the zippered handwarmer pockets out of the way of harness straps and added a stretch woven shell to the collar. As a cold weather mid-layer the R2 is a high performance blend of light weight, compressibility and toasty warmth. It also has a full-length front zipper and a dropped tail. R1 Stretch panels on the sides and at the elbows and cuffs leave your arms free. Made in USA.
