Challenge yourself with the SMAI Weight Vest. The perfect piece of gym equipment to add an extra level of difficulty to your training, the Weight Vest is ideal for cardio conditioning or body weight training. Designed so the weight is evenly distributed, the vest has open sides to allow ventilation to keep you cool while you sweat it out. With the option of adding or removing up to 20 of the 1kg steel blocks, you can push it as hard as you want. Featuring Velcro sides, the Weight Vest is designed to fit snug to ensure no chaffing or rubbing to maximise comfort. The nylon straps that secure the weight have been reinforced to keep the weight secure and as close to the body as possible.
