The X2 Vest is already weighted with 12 lbs of weight for added intensity to any exercise or sport. Additional weight is entirely optional and can be added or removed depending on the exercise and training goal. The more weight you have on your vest, the more calories you burn and the harder you work.
Wear your additional pounds of weight with your X2 Weighted Vest for a fantastically intense workout.
Basically these are only for use with your X2 Weighted Vest, there is no other application so purchase your vest here
