- Neoprene vest with built-in iron and sand weight filling.
- Adjustable straps for ideal fit and comfort.
- One size fits most.
- The added weight of the vest creates additional resistance during muscle building, body-weight exercises, and heart - pumping cardio activities – making you expend more energy to achieve your fitness goals.
- Concentrates the weight in the chest and upper body during training, which works the abdominals and builds core muscle strength.
