The Everlast C3 Foam Heavy Bag with a maximum capacity of 100-Pound is built and designed to provide professional level training for boxers. It is excellent for a great workout for all athletes who box for fitness. The C3 (Contoured Closed Cell Foam Technology) is designed to provide the increased cushioning, support, and force dispersion that serious hitters need during heavy workouts. The high density foam’s closed-cells also inhibit moisture transfer into the foam padding to keep your gloves lighter and drier during use. Meanwhile, the bag’s custom filling of natural and synthetic fibers blended with sifted sand, offers a homogenous feel and resilient shock absorption. Encased within a durable polycanvas shell, the C3 Heavy Bag is built to last. The bag is equipped with a durable webbing system for safety that includes heavy-duty nylon straps and double end loops for solid anchoring. The filled bag comes with approx 75-80 lbs weight.
