The Vecct Second Skin Set is engineered to provide comfort and performance across all conditions. Made from quick-dry 4-way stretch polyester, these tops adapt to your body's temperature, keeping you cool during intense activity and warm when the temperature drops. Designed with long-distance runners in mind, they feature flatlock seams and a tagless design, eliminating internal labels to prevent chafing. The second-skin fit offers compression for muscle support and circulation.
