30 Lb V-MAX Basketball (Black) V-FORCE MAX formerly V-Max, now upgraded and improved to last even longer. "I recommend this weight vest for court sports and overhead arm movements, excellent for basketball and volleyball training. Adds weight for resistance, helping to increase vertical leap. The 2-1/4" wide shoulders help distribute the weight better over your shoulders for a more comfortable workout. All cast iron weights have rounded corners and are coated with the same enamel used by CAT heavy equipment." Lifetime Warranty. 30-Day money-back guarantee*. Made in the USA.
