Long-term cardio and high-intensity athletics. Wearing the G-Vest Sport and G-Tights will provide just enough resistance to test your maximum speeds and most explosive movements, allowing you to break through obstacles and increase game or race day endurance. The G-Vest Sport offers adjustable shoulder straps for torso length and an adjustable side-cinch pull for a precise fit. The front zip and side cords secure in place, a simple touch that makes a big difference during jump lunges and burpees. G-Tights are smooth on the inside and have a solid fit.
