HYPERWEAR Hyperwear, Hyper Vest PRO Weighted Vest Ultra Thin Adjustable Patented Elastic Fabric for Better Fitness Workout, Unisex Fit, Small Steel Weights (9kg, XL)

The Hyper Vest PRO is the weighted vest that trains like gear and fits like clothing. Engineered with USA-made Xyflex performance stretch fabric, it delivers a locked-in compression fit that stays flush to your torso during running, HIIT, walking, and every movement in between. No bounce. No shift. No bulk. Just added resistance that works with your body. The secret is the micro-weight system. Hundreds of galvanized steel weights — each just 2.25 oz — distribute evenly across the vest for a balanced, slim profile you can wear under a t-shirt. Add or remove weights in seconds to fine-tune your resistance for any workout, from a morning walk to a high-intensity circuit. The PRO model offers higher weight capacity than the ELITE, reaching up to 40 lbs in X-Large. Combined with the adjustable side-lacing system and YKK front zipper, this vest fits a wide range of body types for both men and women. The horizontal stretch allows full natural breathing while zero vertical stretch keeps every ounce locked in place. The Hyper Vest PRO has been used in university weight-bearing exercise research, including the studies of speed training for athletes and the impact of weight loss on bone density, muscle mass, and metabolism. Whether you are building functional strength through progressive overload, adding resistance to daily walks for bone-loading exercise for osteopenia, or pushing through rucking and trail workouts, this vest grows with your training. Machine washable. Slim enough to disappear under your clothes. Strong enough for your most demanding sessions.
