- Soft and Breathable: Comfortable fabric feels great on the skin for shirtless or sports bra wear. The ventilated design with air pockets keeps you cool and reduces sweat during long workouts, enhancing comfort and performance by minimizing heat.- Adjustable Comfort: Adapt the width of the shoulders on this adult weighted vest for comfortable feel. The double straps assure you can fine tune the tightness of the fit for close-to-the-body, secure wear.- Storage Pocket: The mesh back pocket stores items during runs to keep hands and pockets clear. The mesh storage space has a capacity to easily accommodate phones and wallets.- Safety First: 17.6 lb. metal sand is sewn evenly into the weighted vest. Wider and thicker shoulder straps reduce vibration and ensure you don't get injured while exercising.
