Slightly Irregular. Fully functional 50lb. attachment. Great shape. Wide shoulders. Comes with additional straps so it will work with any wide shouldered weight vest. Shipping included to USA destinations. Designed to fit your existing 50 lb. weight vest. Includes needed adaptable strap to connect to your weight vest. The way this attachment works is it simply fits over the top of your weight vest, essentially doubling the weight vest. All weights are included with this attachment. The added strap adaptation fits under the flap on the bottom row of your existing weight vest and the attachment velcros to it. It’s very secure and once your belt is attached it will stay put during exercise. Questions? Contact us. We are happy to help you.
