Excellent accessory for the AMILA Raw Vigor vest. The weights are very high quality, made of solid iron, with a perfect fit in the vest’s special pockets. They are easy to insert and remove, without shifting during training, providing excellent stability and balance. The ability to add weight gradually is a major advantage, as you can adjust the training intensity according to your goal. The weights are very well made, show no wear, and retain their shape even after frequent use. I have used them in functional training, pull-ups, push-ups, squats, lunges, and walking with the vest, and their fit remains stable without annoying movement or noise. Combined with the Raw Vigor vest, they make a complete and particularly high-quality solution for anyone who wants to gradually increase resistance and progress their training. I recommend them without reservation.
