Sugoi Piston 140
Here's what other sites are saying:
The Sugoi Women's Piston 140 Long-Sleeve Shirt uses high-tech Piston compression fabric so your muscles work more efficiently and recover faster. Compression fabric strategically holds your muscles in place so there is less vibration and better circulation. The mesh panels keep fresh air on your skin so there is to sweat over, and the flat-panel construction means that chaffing won't be a issue either.
